This instruction manual includes installation, operation,
calibration, maintenance, and parts ordering information for the 3582 Series pneumatic valve positioners,
the Type 3582i electro-pneumatic valve positioner,
and the 3583 Series pneumatic valve stem position
transmitters. Refer to separate instruction manuals for
information on the control valve, actuator, and accessories.
Only personnel qualified through training or experience
should install, operate, or maintain the valve positioner
or valve stem position transmitter. If there are any
questions concerning the instructions in this manual,
contact your Fisher sales office or representative before proceeding.
Description
The 3582 Series pneumatic valve positioners and the
Type 3582i electro-pneumatic valve positioner shown
in figure 1 are used with diaphragm-actuated, slidingstem control valve assemblies. The pneumatic valve
positioners receive a pneumatic input signal from a
control device and modulate the supply pressure to
the control valve actuator. The positioner adjusts the
actuator supply pressure to maintain a valve stem
position proportional to the pneumatic input signal.
Type 3582NS positioners meet typical requirements of
the nuclear power industry. The Type 3582NS
construction includes materials that provide superior
performance at elevated temperature and radiation
levels. The O-rings are EPDM (ethylene propylene)
and the diaphragms are EPDM/Nomex. EPDM
onstrates superior temperature capability and shelf life
over nitrile. The Nomex diaphragm fabric demonstrates improved strength retention at elevated temperature and radiation conditions.

In addition, the Type 3582NS positioner is qualified
“commercial grade dedicated” under Fisher’s
10CFR50, Appendix B, quality assurance program.
These can be supplied as 10CFR21 items.
The Type 3582i is an electro-pneumatic valve positioner, consisting of a Type 582i electro-pneumatic converter installed on a Type 3582 pneumatic valve positioner. The Type 3582i valve positioner provides an
accurate valve stem position that is proportional to a
dc current input signal.
The Type 582i electro-pneumatic converter is a modular unit that can be installed at the factory or in the
field. However, do not plan to install a Type 582i converter on an existing positioner until you contact your
Fisher sales office or representative for application
assistance.
The Type 582i converter receives the dc current input
signal and, through a nozzle/flapper arrangement, provides a proportional pneumatic output signal. This
pneumatic output signal provides the input signal to
the pneumatic valve positioner, eliminating the need
for a remote-mounted transducer.
The 3583 Series pneumatic valve stem position transmitters are for use with sliding-stem diaphragm actuators. These units provide an output signal that is directly proportional to the valve stem position.
Refer to the type number description for a detailed
explanation of type numbers.
The following descriptions provide specific information
on the different valve positioner or valve stem position
transmitter constructions. If the type number is not
known, refer to the nameplate on the positioner. For
the location of the nameplate, refer to key 25 in figure
21.

Installation
Note
All valve positioners and valve stem
position transmitters are shipped with
foam rubber packing material inside the
case. Remove the cover (key 33, figure
21) and the packing material before attempting to operate the unit. Make sure
all vent openings are clear before installation of the unit and that they remain
clear during use.
Typically, the positioner or transmitter is ordered with
the actuator. If so, the factory mounts the valve positioner or valve stem position transmitter and connects
the valve positioner output to the actuator. If a Type
67AFR filter-regulator is specified, it may be integrally
mounted to the valve positioner or valve stem position
transmitter, except for the Type 3582NS positioner.
For the Type 3582NS, the Type 67AFR is separately
mounted, not integrally mounted to the positioner.
Note
In some cases, alignment and calibra-
tion of the valve positioner or valve
stem position transmitter at the factory
may not be possible, and field align-
ment and calibration is required. Before
putting the valve positioner or valve
stem position transmitter into service,
check the operation of the unit to be
sure it is calibrated. If the valve posi-
tioner or valve stem position transmitter
requires alignment or calibration, refer
to the appropriate calibration instruc-
tions in this manual.
If the valve positioner or valve stem position transmitter is ordered separately, disconnected, or removed
from the actuator, refer to the appropriate sections of
this manual for installation information.

Mounting
Key numbers used in this procedure are shown in figure 3 except where indicated.
1. Figure 3 shows the various mounting parts required
for mounting on Fisher actuators. Mounting parts for
Fisher actuators that require spacers have the spacers
(key 50) included. Type 657 and 667 actuators, sizes
70 through 100, with or without a side-mounted handwheel, use spacers (keys 97 and 102) between the
stem connector and the connector arm (key 48). On all
other actuators that use spacers, place the spacers
(key 50) between the mounting plate (key 63) and the
actuator mounting boss.
6
Figure 3. Mounting Assembly
When mounting the valve positioner or valve stem
position transmitter on an actuator by another
manufacturer, provide spacers, if necessary, by cutting sections from 1/2- or 3/8-inch pipe so that the ‘‘X’’
dimension matches the value given in figure 6.
2. As shown in figures 3 and 4, attach the connector
arm (key 48) to the stem connector so that the connector arm extends through the yoke legs on the side
of the lower mounting boss.
3. Attach the valve positioner or valve stem position
transmitter to the mounting plate (key 63) using the
holes shown in figure 5.
4. Mount the Type 67AFR regulator:

3582 Series valve positioners (except Type
3582NS) and 3583 Series valve stem position
transmitters, mount the regulator on the integral boss
on the bypass block.
Type 3582NS valve positioners, use the
mounting plate with provision for separately mounting
the Type 67AFR regulator. Separately mount the positioner and the regulator on the mounting plate.
Type 3582i valve positioners, mount the regu-
lator on the integral boss that is part of the Type 582i
converter housing.
5. As shown in figure 5, the mounting bracket has four
sets of holes for mounting the assembly to the actuator. Refer to table 3 to determine which set of mounting holes to use, then attach the assembly to the lower
mounting pad on the actuator.
CAUTION
To avoid equipment damage, be certain
the connector arm clears the valve positioner or valve stem position transmitter
case as the actuator moves through its
complete stroke.

7. Slip the round end of the travel pin (key 60) into the
rotary shaft arm (key 2) slot as shown in figure 4.
8. Slide the square end of the travel pin into the pin
holder and pin lock (keys 61 and 59). Place the pin
lock and holder into the slot in the connector arm (key
48). Screw the cap nut (key 62) onto the pin lock (key
59), but do not tighten.
9. With the actuator at its mid-travel position, lift the
rotary shaft arm so that the 0-degree index marks on
the rotary shaft arm are aligned with the case index
marks as shown in figure 7.
For standard travel pin setting (that is, with the
travel pin setting equal to total actuator travel). Stroke
the actuator to each end of its travel. At each end of
travel, the 30-degree index marks on the rotary shaft
arm should align with the case index marks. If the index marks are not in line, loosen the cap nut (key 62)
and slide the travel pin (key 60) in the rotary shaft arm
slot until the 30-degree index marks align with the
case index marks. Be sure the travel pin remains perpendicular to the connector arm. After making this adjustment, tighten the cap nut and re-check the arm at
the mid-travel position. If the 0-degree index marks do
CAUTION
not align, repeat this procedure.
Never set the travel pin at a setting that
is less than the actual actuator stroke.
Setting the travel pin at a setting that is
less than the actual actuator stroke will
cause the cam to rotate more than 60
degrees, causing damage to the cam or
other parts.
10. Position the travel pin so that it is perpendicular to
the connector arm and aligns with the correct actuator
stem travel index on the rotary shaft arm. Tighten the
cap nut (key 62 in figure 4).
8
For special travel pin setting (that is, with the
travel pin setting greater than total actuator travel).
Check the index marks using a procedure similar to
the standard settings procedure. The arm will not rotate a full 60 degrees as the actuator is stroked, and
the 30-degree index marks on the cam will be short of
aligning with the case index marks. If necessary, adjust the travel pin position so that the 30-degree marks
are the same distance from the respective case index
mark at each end of actuator travel.

Note
D For Valve Positioners: The small
arrow on the cam must point in the direction of stem movement with increasing actuator diaphragm pressure.
D For Valve Stem Position Transmitters: If the arrow on the cam points up
toward the nozzle, output pressure increases with downward stem movement. If the arrow points down, output
pressure decreases with downward
stem movement.
If the arrow is pointing in the wrong direction, use the following procedure to
remove, reverse, and re-install the cam.
When mounting a valve positioner or valve stem position transmitter, check to see if the correct cam (key 4)
and cam position has been selected. To change the
cam or cam position, unhook the extension spring (key
38), and remove the cam bolt and locking nut (keys 6
and 45). Remove the cam and spring retainer bracket
(key 43).
To install the cam, screw the locking nut all the way
onto the cam bolt. Attach the cam and spring retainer
bracket to the shaft assembly with the cam bolt. Tighten the bolt to secure the cam. Then, tighten the locking nut against the spring retainer bracket. Hook the
spring into the spring retainer bracket.

instrument air quality standards describe acceptable dirt, oil, and moisture
content. Due to the variability in nature
of the problems these influences can
have on pneumatic equipment, Fisher
Controls has no technical basis to recommend the level of filtration equipment
required to prevent performance degradation of pneumatic equipment. A filter
or filter regulator capable of removing
particles 40 microns in diameter should
suffice for most applications. Use of
suitable filtration equipment and the establishment of a maintenance cycle to
monitor its operation is recommended.

Regulator, or equivalent, to filter and regulate supply
air. Except for the Type 3582NS, the filter regulator
can be mounted on the positioner. For the Type
3582NS the regulator can be mounted on the mounting plate with the positioner but not on the postioner.
The supply pressure should be high enough to permit
setting the regulator 5 psi (0.3 bar) above the upper
limit of the appropriate pressure range, for example:
20 psig (1.4 bar) for a 3 to 15 psig (0.2 to 1.0 bar)
range. However, do not exceed the maximum allowable supply pressure of 50 psig (3.4 bar) nor the pressure rating of any connected equipment.
Connect the nearest suitable supply source to the
1/4-inch NPT IN connection on the filter regulator (if
furnished) or to the 1/4-inch NPT SUPPLY connection
on the positioner block assembly.
Output Connection
A factory mounted valve positioner has the valve positioner output piped to the supply connection on the
actuator. If mounting the valve positioner in the field,
connect 3/8-inch tubing between the 1/4-inch NPT
valve positioner connection marked OUTPUT and the
actuator supply pressure connection. Connect the
valve stem position transmitter connection marked
OUTPUT to an instrument that indicates valve stem
position.
Instrument Connection
For a 3582 Series pneumatic valve positioner connect
3/8-inch tubing from the control device to the 1/4-inch
NPT INSTRUMENT connection. If the control device
is mounted on the control valve assembly by the factory, this connection is made.
The Type 3582i electro-pneumatic valve positioner
requires a 4 to 20 milliampere dc current input signal
from the control device. A 1/2-inch NPT conduit connection is provided for properly wiring electrical installations. For more information, see the electrical connections section.
Diagnostic Connections
To support diagnostic testing of valve/actuator/positioner/accessory packages, special connectors and
hardware are available. The hardware used includes
1/8-inch NPT connector bodies and body protectors. If
the diagnostic connectors are ordered for a positioner
with gauges, 1/8-inch stems are also included.
Install the connectors on the 3582 block assembly or
Type 582i housing as shown in figure 9. Before installing the connectors on the positioner, apply sealant to
the threads. Sealant is provided with the diagnostic
connections and hardware.
2. Use a clean, dry, oil-free air supply with instruments containing EPDM components.
EPDM is subject to degradation when exposed to petroleum-based lubricants.

Vent
WARNING
If a flammable, toxic, or reactive gas is
to be used as the supply pressure medium, personal injury or property damage could result from fire or explosion
of accumulated gas or from contact with
toxic, or reactive gas. The positioner/actuator assembly does not form a gastight seal, and when the assembly is enclosed, a remote vent line, adequate
ventilation, and necessary safety measures should be used. A remote vent
pipe alone cannot be relied upon to remove all hazardous gas. Vent line piping should comply with local and regional codes and should be as short as
possible with adequate inside diameter
and few bends to reduce case pressure
buildup.

Electrical Connections for Type 3582i
Valve Positioner
CAUTION
When installing a remote vent pipe, take
care not to overtighten the pipe in the
vent connection. Excessive torque will
damage the threads in the connection.
The vent opening at the back of the case marked
VENT should be left open to prevent pressure buildup
inside the case and to provide a drain hole for any
moisture that might collect inside the case. A screen is
normally installed in this opening to prevent blockage
from debris or insects.
If a remote vent is required, the vent line must be as
short as possible with a minimum number of bends
and elbows. The vent connection is 3/8-inch NPT female. To connect a remote vent, press out the screen
and use 3/8-inch tubing to provide a remote vent. The
582i has a 1/4-inch NPT female vent connection.
WARNING
For explosion-proof applications, disconnect power before removing the
converter housing cap.
For explosion-proof applications, install
rigid metal conduit and a conduit seal
no more than 18 inches (457 mm) from
the converter. Personal injury or property damage might result from explosion if
the seal is not installed.
For intrinsically safe installations, refer
to the loop schematics at the end of this
manual, factory drawings, or to instructions provided by the barrier manufacturer for proper wiring and installation.
Use the 1/2-inch NPT conduit connection on the Type
582i converter housing for installation of field wiring.
For Class I, Division I explosion-proof applications,
install rigid metal conduit and a seal no more than 18
inches (457 mm) from the converter. Also, install conduit according to local and national electrical codes
which apply to the application.
Also, be certain that the exhaust holes in the relay
(key 32 in figure 21) are kept open.

WARNING
Avoid personal injury from sudden release of process pressure. Before
mounting the Type 582i converter:
D Disconnect any operating lines providing air pressure or a control signal to
the actuator. Be sure the actuator cannot suddenly open or close the valve.
D Use bypass valves or completely
shut off the process to isolate the valve
from process pressure. Relieve process
pressure on both sides of the valve.
Drain the process media from both
sides of the valve.
If a 3582 Series pneumatic valve positioner has previously been installed using a mounting plate with a
five-hole mounting pattern (positioner to mounting
plate), either at the factory or in the field, it can be upgraded to a Type 3582i electro-pneumatic valve positioner by installation of a Type 582i converter. To
install a Type 582i converter, refer to the following instructions.
Note
Inspect the existing valve positioner to
determine the input signal range. If the
input signal range is not 3 to 15 psig,
refer to the appropriate sections of this
manual describing input signal ranges
and how to change the range spring.
1. Inspect the positioner mounting plate. Be certain
that five screws fasten the positioner to the mounting
plate. Two additional screws fasten the plate to the
actuator.
When the positioner is correctly attached to the
mounting plate, proceed with the installation by taking
the control valve/actuator/positioner package out of
service.
2. Properly vent the actuator loading pressure and the
supply pressure. Disconnect the pressure tubing connections to the valve positioner.
3. Please contact your Fisher sales office or representative before planning to upgrade any existing 3582 Series valve positioner by field installation of a Type 582i
electro-pneumatic converter. Also, refer to this section of the instruction manual
which describes field installation of a Type 582i converter.
13
3582 and 3583 Series
3. Remove the two screws (key 105 in figures 24 or
25) holding the bypass block (key 34A in figures 24 or
25) to the valve positioner case and remove the bypass block. Save the screws to reattach the Type 582i
converter.
4. Remove and discard the existing gasket (key 104
in figures 24 or 25) between the bypass block and
valve positioner case.
5. Unpack the Type 582i converter to be installed.
6. Position the new gasket on the Type 582i converter
as shown in figure 27. Insert the existing screws (key
105 in figures 24 or 25) through the appropriate holes
in the Type 582i converter housing and new gasket.
7. Mate the converter and new gasket to the side of
the valve positioner case using the alignment pins on
the converter housing.
8. Tighten the screws.

Valve Positioner Cam Information
Note
The small arrow on the valve positioner
cam must point in the direction of stem
movement with increasing actuator diaphragm pressure. If the arrow is pointing in the wrong direction, remove, reverse, and re-install the cam.
Isolate the control valve and shut off
pressure lines to the valve positioner.
Refer to figure 21 for key number locations. Unhook the spring (key 38), and
remove the cam bolt and locking nut
(keys 6 and 45). Remove the cam (key 4)
and spring retainer bracket (key 43). To
install the cam, screw the locking nut all
the way onto the cam bolt. Attach the
cam and spring retainer bracket with the
cam bolt. Tighten the bolt to secure the
cam. Then, tighten the locking nut
against the spring retainer bracket.
Hook the spring into the spring retainer
bracket.
When shipped from the factory, 3582 Series valve positioners and the Type 3582i valve positioner have a
linear cam, Cam A, installed in the operating position.
Two characterized cams, Cams B and C, are available. These characterized cams may be used to
modify the valve flow characteristics.
Figure 13 shows resultant stem travel due to an incremental instrument pressure change for each cam. In
figure 13, the curves are based on 60 degrees cam
rotation for 100 percent stem travel. At 50 percent of
the input signal span, for example, the stem will travel
50 percent with cam A, 68 percent with cam B, and 32
percent with cam C. Figure 14 shows how the flow
characteristics change when using the cams with a
valve that has equal percentage characteristics. Figure
15 shows how the flow characteristics change when
using the cams with a valve that has linear characteristics.
When cam A is the operating cam, there is a linear
relationship between an incremental instrument pressure change and the resultant valve stem travel. The
flow characteristic is that of the control valve. Installing
either cam B or C as the operating cam, changes the
relationship between the incremental instrument pressure change and valve stem travel, thereby modifying
the valve flow characteristic.

Valve Positioner Bypass Operation
Type 3582 and 3582D valve positioners, and Type
3582NS positioners with bypass, are supplied with a
bypass assembly. A handle on the bypass assembly
permits selecting positioner or bypass operation. Refer
to figure 24 for key number locations.

Information
Note
If the small arrow on the valve stem
position transmitter cam points up toward the nozzle, output pressure increases with downward stem movement. If the arrow points down, output
pressure decreases with downward
stem movement. If the arrow is pointing
in the wrong direction, remove, reverse,
and re-install the cam.
Isolate the control valve and shut off
pressure lines to the valve positioner.
Refer to figure 21 for key number locations. Unhook the spring (key 38), and
CAUTION
Do not use bypass when the valve positioner is reverse-acting or is in splitrange operation. In these cases, bypassing the valve positioner sends the input
signal directly to the actuator. Such a
change will affect the desired operation
and possibly upset the system. Use bypass only when the input signal range is
the same as the valve positioner output
range required for normal actuator operation.
Labels on the bypass block (key 34A) and a pointer on
the bypass handle (key 34D) indicate if the input signal
from the instrument goes to the positioner or directly to
the control valve actuator. Push the bypass handle
toward the back of the positioner to move the pointer
over the word POSITIONER. With the bypass handle
in this position, the input signal goes to the valve positioner bellows and the output pressure of the valve
positioner goes to the actuator. Pull the bypass handle
forward to move the pointer over the word BYPASS.
In this position, the input signal goes directly to the
actuator.

Note
A difference between the input signal

bump in the controlled system when the
bypass handle is moved to BYPASS.
With a reverse-acting or split-range valve positioner,
the bypass handle may be locked in the POSITIONER
position so that bypass cannot be used. To lock the
bypass handle in the POSITIONER position, first shut
off the instrument and supply pressure to the valve
positioner. Then, remove the hex head shoulder screw
from the center of the handle. Remove the handle and
rotate it 180 degrees and re-install it with the handle
between the two lugs cast on the bypass block. Replace the shoulder screw.
Input Signal Ranges
Standard input signal ranges for valve positioners and
valve stem position transmitters are shown in table 4.
Changing from one standard range to another requires
changing the range spring. To change the range
spring, refer to the instructions for changing the range
spring in the maintenance section of this manual. Splitrange operation of 3582 Series valve positioners or
the Type 3582i valve positioner normally does not require changing the spring. Refer to the section below
for split-range information.
Valve Positioner Split-Range Operation
The 3582 Series valve positioners and the Type 3582i
valve positioner are suitable for split-range operations.
In split-range operation, the input signal, either pneumatic or dc current, from a single control device is split
between two or more control valves. No additional
parts are required to use an existing valve positioner
for split-range operation.
Table 5 shows some typical split-ranges for the valve
positioners.

To change to split-range operation, perform the beam
alignment procedures then perform the calibration procedure using the desired split range inputs that result
in full valve travel. For example, for a 3582 Series positioner with a 3 to 15 psig (0.2 to 1.0 bar) input signal
range in a two-way split, a 9 psig input signal should
completely stroke the valve for a 3 to 9 psig signal
range.
Note
The flapper must approach the nozzle
squarely at the midpoint value of the input signal range for proper operation.
On some applications where the input
signal span is comparatively small (as
found with split-range applications), the
nozzle adjustment may not be enough
to set the proper starting point. Also,
some difficulty may be experienced in
keeping a valve positioner from unloading when the input signal continues to
increase above the split-range.
For example, for a 3 to 9 psig (0.2 to 0.6
bar) input signal range, the input signal
could increase to 15 psig (1.0 bar). Continued bellows travel due to the increased input signal over the split-range
would drive the flapper into the nozzle.
The impact could possibly cause mis-
16
3582 and 3583 Series
alignment between the flapper and
nozzle. Such a misalignment, in turn,
could affect split-range calibration.
In these cases, adjust the follower assembly screw in addition to the nozzle
adjustment to obtain satisfactory results.
Note
The 3582 Series valve positioners require a relatively small percentage of the
instrument pressure span to obtain full
valve travel. With the travel pin set to
equal the valve travel, the input signal
change required to fully stroke the valve
can be reduced to 33 percent of normal
input signal change. With the travel pin
set to a value greater than the valve travel, the input signal change required to
fully stroke the valve can be reduced to
a minimum of 20 percent of normal input signal change.
2. Screw the locking nut (key 45) all the way onto the
cam bolt.
Note
If the arrow stamped on the cam points
toward the nozzle, output pressure increases with downward stem movement. If the arrow points down away
from the nozzle, output pressure decreases with downward stem movement.
3. Reverse the cam (key 4) from its original position.
Attach the cam and spring retainer bracket with the
cam bolt. Tighten the cam bolt to secure the cam.
Then tighten the locking nut against the spring retainer
bracket.
4. Hook the spring into the spring retainer bracket.
5. After reversing the cam, perform the calibration
procedures in the calibration of valve positioners and
transmitters section.
Changing Valve Positioner Action
Converting a 3582 Series valve positioner or Type
3582i valve positioner from direct acting (an increasing
input signal, either pneumatic or electrical, increases
output pressure) to reverse acting (increasing input
signal decreases output pressure) or vice versa requires no additional parts. The position of the flapper
assembly on the beam determines the action. As
shown in figure 16, the beam is divided into quadrants.
The direct-acting quadrant of the beam is labeled DIRECT and the reverse-acting quadrant is labeled REVERSE. To change the positioner action, simply move
the flapper assembly to the opposite quadrant of the
beam. Perform the calibration procedures in the valve
positioner calibration section.
Changing Valve Stem Position
Transmitter Action
Refer to figure 21 for key number locations unless
otherwise indicated.
The flapper of the 3583 Series valve stem position
transmitter is always positioned in the reverse-acting
quadrant as shown in figure 20. To reverse the signal,
reverse the cam as follows:
1. Unhook the spring (key 38), and remove the cam
bolt (key 6), cam (key 4), and spring retainer bracket
(key 43).
Calibration Of Valve Positioner Or
Valve Stem Position Transmitter
Note
The following beam alignment and calibration procedures are applicable for
both the 3582 Series and the Type 3582i
valve positioners and 3583 Series valve
stem position transmitters.
Beam Alignment
Note
The beam is leveled at the factory prior
to shipment. Once the beam is leveled,
no additional leveling should be required unless the beam pivot pin or the
bellows assembly pivot pin are
changed, the bellows assembly or range
spring are replaced, or the valve positioner is changed to split range operation.
The purpose of beam alignment is to ensure the correct mechanical position of parts so the valve positioner can be calibrated. Provide the appropriate supply
pressure. Also, provide an input signal to the positioner which can be manually set at the midpoint of the
desired input signal range.

Refer to figure 16 for parts locations. Refer to figure 21
for key number locations unless otherwise indicated.
Position the flapper assembly by hand to different settings on the beam assembly or by using a screwdriver
in the slot of the flapper setting adjustment.
To level the beam, proceed as follows:
Note
In the following steps, if the required
rotary shaft arm position cannot be attained when adjusting a pivot point, adjust one of the other pivot points slightly. Then, repeat the original pivot
adjustment. Continue this process until
the required arm position can be attained.
1. Stroke the actuator to its mid-travel position with a
handwheel or a manual loader. Refer to figures 4
and 7. Lift the rotary shaft arm (key 2) so that the
0-degree index marks on the rotary shaft arm align
with the case index marks as shown in figure 7. Then,
position the travel pin (key 60) so that it is perpendicular to the arm and aligns with the appropriate total actuator travel index mark on the rotary shaft arm. Tighten the locking nut (key 62).
Valve stem travels less than 1-1/8 inches
(29 mm) require that the travel pin be set
at the 1-1/8 inches travel index mark on
the rotary shaft arm.
2. Loosen the nozzle locknut and turn the nozzle
clockwise to its lowest position. Then screw the nozzle
out (counterclockwise) approximately 2 turns and tighten the locknut.
Note
For proper operation, the flapper must
approach the nozzle squarely. Inspect
the nozzle/flapper alignment. Be sure
the flapper is not loose, bent, or twisted.
3. Remove any loading pressure and/or disengage
any handwheel used to position the actuator. Connect
the necessary tubing from the valve positioner output
to the actuator pressure connection.
4. Connect the input to the valve positioner and set
the input signal value at midrange. For example, for a
3582 Series valve positioner with a 3 to 15 psig (0.2 to
1.0 bar) input signal range, set the input signal at 9
psig (0.6 bar). Then apply supply pressure to the valve
positioner.
5. Move the flapper assembly to zero on the beam
scale. The 0-degree index marks on the rotary shaft
arm should align with the case index marks as shown
in figure 17. If not, loosen the follower assembly screw
locknut and adjust the follower assembly screw until
the 0-degree index marks on the rotary shaft arm align
with the case index marks. Tighten the locknut.

6. Move the flapper assembly to position 10 on the
direct-acting side of the beam scale. The 0-degree

the case index marks as shown in figure 17. If not,
loosen the bellows assembly locknut and adjust the
bellows pivot pin until the 0-degree index marks on the
rotary shaft arm align with the case index marks.
Tighten the locknut.
7. Move the flapper assembly to the left to position 10
on the reverse-acting side of the beam. The 0-degree
index marks on the rotary shaft arm should align with
the case index marks as shown in figure 17. If not,
loosen the beam pivot pin locknut and adjust the beam
pivot pin until the 0-degree index marks on the rotary
shaft arm align with the case index marks. Tighten the
locknut.
8. Repeat steps 5, 6, and 7 to optimize alignment.
Recheck to make sure the flapper approaches the
nozzle squarely. If it does not, adjust the nozzle and
re-level the beam. After alignment, the valve positioner
is ready for calibration.
Calibration
1. Shut off the supply pressure to the valve positioner.
Connect or reconnect the necessary tubing from the
valve positioner output to the actuator supply connection. Connect the input to the valve positioner and set
the input signal value at midrange.
2. Move the flapper assembly to approximately position 6 in the proper operating quadrant of the beam
(direct or reverse acting), and apply supply pressure to
the valve positioner. The 0 degree index marks on the
rotary shaft arm should align with the case index
marks as shown in figure 17 and the actuator should
be at its midtravel position. If not, first check for loose
linkage or improper cam installation. A minor nozzle
height adjustment might be necessary to make the
desired input signal value correspond to the starting
point of travel.
3. Apply an input signal equal to the low value of the
input signal range. For example, for a 3582 Series
valve positioner with a 3 to 15 psig (0.2 to 1.0 bar) input signal range, set the input signal at 3 psig (0.2
bar). Loosen the nozzle locknut and adjust the nozzle
until the actuator moves to the proper end of its travel.
Changing the nozzle position is intended only as a
means of zero trim adjustment. Whenever nozzle position is changed, the zero reference point is changed.
4. Apply an input signal equal to the high value of the
input signal range and observe the actuator stem travel. If the stem travel is short of its expected range, increase the travel by moving the flapper assembly to a
higher number on the beam. If the desired stem travel
occurs before the input signal reaches the high value
of the input signal range, decrease the travel by moving the flapper assembly toward a lower number on
the beam.
5. Repeat steps 3 and 4 until the correct travel is
achieved. Each time the flapper position is changed in
step 4, repeat step 3 to provide proper zero.
Moving the flapper assembly toward zero on the beam
scale decreases stem travel. Table 6 lists the minimum stem travel available for different travel pin settings. For example, with a travel pin setting of 2 the
minimum stem travel possible, for the full input signal
range, would be 7/16-inch (11 mm).
Principle of Operation
3582 Series Valve Positioners
The 3582 Series (the Type 3582, 3582NS and Types
3582A, C, D, and G pneumatic valve positioners) accept a pneumatic input signal from a control device.
Figure 18 is an operational schematic for a direct-acting pneumatic valve positioner.
As shown in figure 18, in a diaphragm-actuated, sliding stem control valve package with a 3582 Series
valve positioner, supply pressure is connected to the
Type 83L relay. A fixed restriction in the relay limits
flow to the nozzle so that when the flapper is not restricting the nozzle, air can bleed out faster than it is
being supplied.
The input signal from the control device is connected
to the bellows. When the input signal increases, the
bellows expands and moves the beam. The beam pivots about the input axis moving the flapper closer to
the nozzle. The nozzle pressure increases and,
through relay action, increases the output pressure to
the actuator. The increased output pressure to the actuator causes the actuator stem to move downward.
Stem movement is fed back to the beam by means of
a cam. As the cam rotates, the beam pivots about the
feedback axis to move the flapper slightly away from
the nozzle. The nozzle pressure decreases and reduces the output pressure to the actuator. Stem
movement continues, backing the flapper away from
the nozzle, until equilibrium is reached.

3583 Series Valve Stem Position
Transmitters
When the input signal decreases, the bellows contracts (aided by an internal range spring) and the
beam pivots about the input axis to move the flapper
away from the nozzle. Nozzle pressure decreases and
the relay permits the release of diaphragm casing
pressure to atmosphere. The actuator stem moves
upward. Through the cam, stem movement is fed back
to the beam to reposition the flapper closer to the
nozzle. When equilibrium conditions are obtained,
stem movement stops and the flapper is positioned to
prevent any further decrease in diaphragm case pressure.
The principle of operation for reverse acting units is
similar except that as the input signal increases, the
diaphragm casing pressure is decreased. Conversely,
a decreasing input signal causes an increase in the
pressure to the diaphragm casing.
Type 3582i Valve Positioner
As shown in figure 19, the Type 3582i electro-pneumatic valve positioner has a Type 582i electro-pneumatic converter attached to the valve positioner. The
582i contains an I/P module which provides a pneumatic output proportional to a dc current input signal.
The dc current input operates coils in a force balanced
beam system which in turn, control bleed air through
an integral nozzle/flapper arrangement. The nozzle
pressure provides the pneumatic input signal pressure
used by the pneumatic valve positioner.
3583 Series (Type 3583, 3583C) pneumatic valve
stem position transmitters are mechanically linked to
the valve stem in a diaphragm-actuated, sliding-stem
control valve package. A change in the position of the
valve stem changes the output pressure produced by
the position transmitter. This signal is then piped to a
reporting or recording device to indicate valve stem
position.
The action of a valve stem position transmitter can be
changed by reversing the internal cam. The valve
stem position transmitter cam is supplied with an arrow stamped on one side. The cam can be positioned
to obtain either increasing or decreasing output pressure with downward stem motion. If the cam arrow
points toward the nozzle, the output pressure increases; if the cam points away, the output pressure
decreases with downward stem motion.
Figure 20 depicts a diaphragm actuator which produces downward stem motion for increasing actuator
pressure. For a stem position transmitter, the flapper
assembly is always positioned in the reverse-acting
quadrant of the beam. Supply pressure is connected
to the Type 83L relay. A fixed restriction in the relay
limits flow to the nozzle so that when the flapper is not
restricting the nozzle, air can bleed out faster than it is
being supplied.
As the pressure to the diaphragm actuator increases,
the valve stem moves downward, causing the internal
cam to rotate. Cam rotation causes the beam to pivot
about the input axis moving the flapper closer to the
nozzle. The nozzle pressure increases which, through
relay action, increases the output pressure.

The output pressure is also connected to the bellows.
As the output pressure increases, the bellows expands, causing the beam to pivot about the feedback
axis moving the flapper slightly away from the nozzle
until equilibrium is reached. The position transmitter
output pressure is now proportional to the valve stem
position.
As the pressure to the diaphragm actuator decreases,
the valve stem moves upward, causing the internal
cam to rotate. Cam rotation causes the beam to pivot
about the input axis moving the flapper away from the
nozzle. The nozzle pressure decreases which, through
relay action, decreases the output pressure. The bellows contracts, causing the beam to pivot about the
feedback axis and moving the flapper closer to the
nozzle until equilibrium is reached. The position transmitter output pressure is again proportional to the
valve stem position.
Maintenance
3582 and 3583 Series
cannot suddenly open or close the
valve.
Use bypass valves or completely
shut off the process to isolate the valve
from process pressure. Relieve process
pressure on both sides of the valve.
Use lock-out procedures to be sure
that the above measures stay in effect
while you work on the equipment.
For explosion proof applications, disconnect power before removing the
converter housing cap in an explosive
atmosphere.
Due to normal wear or damage from external sources
(such as debris in the supply medium), periodic maintenance or repair of the valve positioner or valve stem
position transmitter may be necessary. Maintenance
of these units consists of troubleshooting, removal for
inspection, and replacement of component parts.
CAUTION
When replacing components, use only
components specified by Fisher Controls. Substitution with other components may result in the positioner or
transmitter no longer meeting safety
certification requirements. Also, always
use proper component replacement
techniques. Improper techniques and
poor quality repairs can impair the safety features of the device.
In case of operational difficulties, the valve positioner
or valve stem position transmitter should first be
checked to see that adjustments have been properly
made. All pressure lines and connections should be
checked for leaks.
The pneumatic relay and gaskets should also be inspected and replaced if necessary. If necessary, clean
or replace the relay restriction. Remove the restriction
assembly (key 9 in figure 26). Clean the restriction,
install a new O-ring (key 14 in figure 26) if necessary,
and replace the restriction assembly.
W ARNING
Avoid personal injury from sudden release of process pressure. Before performing any maintenance operations:
Disconnect any operating lines providing air pressure, or a control signal
to the actuator. Be sure the actuator

Changing the Range Spring
Unless otherwise noted, key number locations are
shown in figure 21.
The range spring is inside the bellows assembly. Standard range spring data is given in table 4. When an
input signal range is split to operate two or more control valves, normally changing the range spring is not
necessary. The input signal range for the range spring
is stamped on the nameplate.
Perform the following procedure to change the range
spring in a valve positioner or valve stem position
transmitter.
1. Unhook the extension springs (keys 27, 77) from
the beam (key 29).
2. Loosen and remove the two screws (key 13), and
lock washers (key 12) that hold the bellows assembly
(key 7) in place.
A gasket (key 34C) is located behind the bypass handle (key 34D) of the 3582 Series valve positioners or
manifold (key 34D) of the 3583 Series valve stem
position transmitters.
1. Remove the screw (key 34G), and lift out the bypass handle or manifold.
2. Remove the gasket.
3. Apply lubricant (key 94) to both sides of the replacement gasket when used with the bypass assembly of the 3582 Series valve positioners. Do not apply
lubricant to the gasket when the bypass assembly is
not used.
4. Set the new gasket in place on the four locating
pins and replace the bypass handle or manifold.
The case gasket (key 104) is located between the
case (key 1 in figure 21) and the bypass block (key
34A) in a 3582 Series valve positioner or a 3583 Series valve stem position transmitter or the housing of
the Type 582i converter (key 1 in figure 27).
5. Remove the two mounting screws (key 105 in figures 24 and 25; key 11 in figure 27) that hold the bypass block or converter housing to the case and remove the unit to expose the case gasket.
6. Install a new gasket and replace the bypass block
or converter housing.
3. Lift out the beam and bellows assembly. Be careful
not to lose the small O-ring (key 11).
4. Loosen the machine screw (key 10), and remove
the range spring (key 8).
5. Install a new range spring, making sure the small
end of the spring is against the spring seat (key 9).
Replace the spring seat and tighten the screw.
6. If the O-ring (key 11) is worn or damaged, replace
it with a new one after applying lubricant (key 94).
Make sure the O-ring is in place, then install the bellows assembly, securing it with two mounting screws
and lock washers.
7. Install the beam over the pivots and hook the
springs to the beam.
8. Make any minor adjustments that may be necessary to re-level the beam as outlined in the beam
alignment procedures of the valve positioners or the
valve stem position transmitters calibration section.
After leveling the beam, calibrate the unit according to
the appropriate calibration instructions.
Replacing Gaskets
Unless otherwise noted, key numbers used in this procedure are shown in figures 24 and 25.
Replacing the Nozzle O-Ring
Unless otherwise noted, key numbers are shown in
figures 22 and 23.
1. Remove the two screws (key 19C) that hold the
flapper and follower assembly (keys 19B and 19G) to
the adjustment arm (key 19A).
CAUTION
For proper operation, be careful not to
bend or twist the flapper or nick the
nozzle orifice during reassembly.
2. Carefully remove the flapper and follower assembly
for access to the nozzle (key 18 in figure 21).
3. Loosen the locking nut (key 71), and unscrew the
nozzle (key 18).
4. Remove the locking sleeve (key 72) from the
nozzle adaptor (key 3). The nozzle adaptor is bonded
to the positioner case with adhesive (key 96) and
should not be removed.

sure the letter ‘‘T’’ on the flapper is visible from the
front of the positioner or transmitter.
8. Perform the beam alignment and calibration procedures in the Calibration of Valve Positioner or Valve
Stem Position Transmitter section.
Removing and Replacing the Relay
Use the following procedure when removing or replacing a relay assembly that requires maintenance, or
when installing a replacement relay assembly. Refer to
figure 26 for key number locations.
1. For valve positioners using a bypass, direct action,
and a full-range input signal, place the positioner in
bypass operation by moving the bypass handle to BYPASS. Then, shut off the supply pressure. For all other valve positioners and valve stem position transmitters, isolate the control valve from the system and
shut off all pressure lines.
Note
A difference between input and valve
positioner output pressure could cause
a transient bump in the controlled system when the bypass handle is moved
to BYPASS.
2. Remove the Type 83L relay (key 32 in figure 21)
from the back of the case by loosening the two mounting screws (key 10).
3. Reinstall the new relay assembly on the case, making sure the O-rings (keys 13 and 15) are in place.
Secure with the two mounting screws (key 10).
4. Resume operation by moving the bypass handle to
the POSITIONER position or by connecting the valve
positioner or valve stem position transmitter and control valve to the system.
Relay Maintenance

3. Inspect and replace the filter cartridge (key 23).
Removing the Type 582i Converter
During the following converter removal procedures,
refer to figure 27 for key number locations.
CAUTION
The I/P module should never be disassembled because the magnetism in the
coils will decrease permanently. If troubleshooting or alignment attempts indicate a faulty I/P module, replace the
module or return the converter to your
Fisher sales representative or sales office for repair.
Note
To check the operation of the I/P module, remove the pipe plug (key 12), and
connect a pressure gauge. Provide a 20
psig supply pressure to the converter.
With a 4-milliampere input signal the
pressure output should read 2.3 to 3.5
psig (0.16 to 0.24 bar). With a 20-milliampere input signal the pressure output
should read 14.0 to 15.5 psig (0.96 to
1.07 bar).
1. Turn off the input signal to the converter. Release
all supply pressure from the valve positioner.
2. Remove the housing cap (key 2).
3. Note the location of the wires, disconnect the field
wiring from the terminal block. Disconnect the grounding wire from the external ground screw (key 10).
4. To remove the I/P module, remove the two screws
(key 9), and pull the module out of the housing. Inspect the O-ring (key 6) and replace it, if necessary.
Apply lubricant (key 15) to the O-ring before replacing.
a. To remove the entire Type 582i converter from
the Type 3582i valve positioner, continue with
steps 5 through 7.
b. To replace the I/P module only, obtain a replacement I/P module listed in the parts list and
refer to the procedures for reassembling the Type
582i converter.

5. Disconnect the supply tubing, output tubing, and
electrical conduit from the converter.
6. If necessary, remove the Type 67AFR regulator by
removing the two screws (key 13). Then, remove the
regulator from the converter assembly. Inspect the
O-ring (key 3) and replace it if necessary. Apply lubricant (key 15) to the O-ring before replacing.
7. Remove the two screws (key 11) holding the Type
582i converter to the valve positioner case. Remove
3582 and 3583 Series
the converter from the valve positioner case (key 1 in
figure 21). Inspect the gasket (key 20) and replace it if
necessary.
Reassembling the Type 582i Converter
During the following converter reassembly procedures,
refer to figure 27 for key number locations.
1. If the Type 582i converter was removed from the
valve positioner, install a new gasket (key 20) between
the converter housing and the valve positioner case.
Attach the converter housing to the valve positioner
case with the screws (key 11) and tighten the screws.
2. If the I/P module was removed from the Type 582i
converter, reinstall the I/P module in the converter
housing. Secure the I/P module with the two screws
(key 9).
3. If other valve positioner components are removed,
refer to the appropriate reassembly procedures and
assemble the valve positioner completely.
4. Reconnect the supply tubing, output tubing, and
conduit to the valve positioner.
5. Reconnect the wiring to the terminal block. Do not
overtighten the terminal screws. Maximum torque is 4
lbfin. (0.45 Nm). Reconnect the grounding wire to
the housing ground screw (key 10) and replace the
cap (key 2).
Note
To check the operation of the I/P module, remove the pipe plug (key 12), and
connect a pressure gauge. Provide a 20
psig supply pressure to the converter.
With a 4-milliampere input signal the
pressure output should read 2.3 to 3.5
psig (0.16 to 0.24 bar). With a 20-milliampere input signal the pressure output
should read 14.0 to 15.5 psig (0.96 to
1.07 bar).
6. Plug the output connection and apply 35 psig (2.4
bar) to the supply pressure connection.
8. Check for leaks using a soap solution. Check any
components which were disassembled or disconnected.
