Description
The 1035 actuator is a rack-and-pinion, pneumatic quarter-turn actuator. The actuator utilizes a double rack and single
pinion design (see figure 2). The actuator uses three carbon filled PTFE guide bands, with a balanced piston which
prevents metal-to-metal contact between the pistons and cylinder wall.
The E Series actuator uses a recessed bushing inserted into the end of the actuator drive shaft. Standard recessed
double-D bushings match the A41 valve drive shaft. In most applications, the valve shaft is inserted directly into the
recessed actuator shaft bushing. The P Series actuators provide a recessed s quare output shaft for coupling the
actuator to the valve shaft. The A41 valve uses a square-to-double-D drive coupler construction. Optional couplings
are available for other applications.

Installation
When an actuator and a valve are shipped together, the actuator is normally mounted on the valve. Follow the valve
body instructions when installing the control valve in the pipeline. If the actuator is shipped separately from the valve
or if it is necessary to mount the actuator on the valve, perform the procedures in the Actuator Mounting section.
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
To avoid personal injury or property damage caused by bursting of pressure-retaining parts, be certain the service
conditions do not exceed the limits given in table 1. Use pressure-limiting devices or pressure-relieving devices to prevent
the cylinder pressure from exceeding these limits.
If hoisting the valve and actuator assembly or the actuator by itself, take precautions to prevent people from being injured
in case the hoist or sling slips unexpectedly. Refer to table 3 for actuator weights. Carefully position the sling to prevent
damage to tubing or any accessories.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.

Actuator Mounting
Use the following steps to connect a valve and actuator that has been ordered separately.
The 1035 E Series is offered with a Double D insert as standard to allow direct coupling to the A41 valve drive shaft. A
few actuator/valve combinations will require the use of an external coupler: E100 with a 1-inch drive shaft, E200 and
E350 with a 1-1/2-inch drive shaft.
P Series applications, the actuators feature an ISO 5211 recessed square drive shaft and requires an external coupler to
engage the valve drive shaft. P Series actuators also require the use of a Limit Stop Plate (LSP) if a Fisher 1080
Declutchable Manual actuator is not being used.
Assemble the bracket, actuator, LSP (if necessary) and valve assembly as follows:
1. Rotate the valve drive shaft to the position necessary to match the valve/actuator operation. See figure 3 for
mounting style codes and positions.
2. Attach the yoke/mounting bracket to the actuator or the LSP (if necessary). Do not fully tighten cap screws at this
time. You will need to align the valve and actuator, or valve, coupler, LSP and actuator before tightening the
mounting screws to the required torque. The 5/8-inch screws should not be used to mount the actuator to the
yoke/mounting bracket. These screws are only to be used for mounting the LSP. Only the 3/4-inch screws are to be
used to mount the actuator to the yoke/mounting actuator.
WARNING
Exceeding any torque requirement may impair the safe operation of this actuator by causing broken or damaged parts.
Refer to table 4 for bolting torque requirements.
The LSP, if used, will also have to be attached to the 1035. Use 4 screws for size P2500/P2505 and 8 screws for size
P4000/P4005. The bolting torque for these 5/8-inch screws will be 10.2 NSm(90inSlb).
3. The P Series and a few E Series actuator combinations require a coupler. Insert the square end of the coupler into
the drive shaft recess in the actuator, making sure the coupler engages properly.
4. Lower the actuator, and coupling assembly onto the valve, making sure that the male valve stem engages into the
coupler or insert.
a. Secure the mounting bracket to the valve using cap screws and lock washers provided in the mounting kit.
b. At this time, make sure that the actuator is in the operation mode desired, and that the valve is in the correct
position required foryourapplication.
5. For E Series actuators with A41 valves, insert the valve drive shaft end (double-D) into the recessed insert.
6. Align the valve shaft with the actuator drive shaft by changing the positioning on the mounting bracket between
them.

Operation
Units supplied from the factory as an assembly are adjusted per specifications supplied to the factory on the original
order.
Unless the valve/actuator assembly has been damaged during shipment, or the actuator removed for maintenance,
the assembly should be factory adjusted and ready for service.
Actuator Orientation: The 1035 actuator is normally installed with its major axis parallel to the pipeline (see code A,
figure 3). However, the actuator can also be oriented 90 degrees to thepipeline.Seefigure3forstandardandoptional
orientations. (Note: Code B is not available in the E Series.)
The P or E Series actuator drive shaft turns a full 90 degrees and the stroke is adjustable for the valve closed position.
When necessary, refer to the actuator adjustment steps in this manual.
Note
The A41 High Performance Butterfly valve should not be turned by the power actuator more than 90 degrees of rotation.
Pre-adjust actuator stops to limit travel to 90 degrees or less until adjustment steps are completed.
Adoubleactingactuatorcanbechangedinthefieldtoaspringreturn unit, or vice-versa (requires different end caps).
Code A actuators can be converted to a code D unit by turning the pistons 180 degrees from the position shown for
code A (See figure 3 for piston and shaft orientation).
Adjustments
ESeriesactuatorsprovide end cap adjustment screws to limit outward travel of the piston. The inward movement of
the piston is limited by the housing stop (see figure 4).
PSeriesactuatorshave a Limit Stop Plate option (LSP) which is used with standard actuator constructions. The LSP is
not used when a Fisher 1080 is used. T he LSP, or the 1080, limits travel in either direction for any construction. Refer to
figure 4.
To adjust the travel stops, refer to the valve instruction manual for open and closed positions of the valve. Upon
assembly, ensure that the power actuator does not drive the valve past 90 degrees of rotation. Valve component parts
can be damaged if high actuator air pressure is applied past 90 degrees. Travel limits must be set in the actuator, not in
the valve. It is recommended that the valve be out of the pipeline when adjusting travel limits.

Troubleshooting
If the actuator does not function, make the following checks:
1. Check for worn teeth on piston racks, if the actuator exhibits excessive amounts of backlash. If worn, replace
piston/gear rack assembly.
2. Check supply pressure to ensure the air supply is reaching the actuator. Place a gauge in the line at the inlet of the
actuator. Monitor the gauge for unexpected pressure drops when operating pressure is applied to the actuator.
3. Check piston seal leakage. For spring return actuators , piston seal leakage will show at port B when port A is
pressurized. For double acting actuators, piston seal leakage will show at port B when port A is pressurized, or vice
versa.
4. Check actuator movement. Remove the actuator from the valve. Apply reduced air pressure [0.7 to 1.0 bar (10 to
15 psi) for double acting, or 1.4 to 2.0 bar (20 to 30 psi) for spring return] to see if the actuator will cycle under a
no-load condition.
D If the actuator cycles under a no-load condition, please refer to the valve instruction manual for valve
troubleshooting or contact your Emerson Process Management sales office.
D If the spring set number is 5 or 6, it may not cycle with the reduced air pressure amounts listed above and may
require retesting with up to 5.5 bar (80 psi) to stroke a full 90 degrees.
D If the actuator does not
cycle, disassemble the actuator using the Actuator Disassembly procedures. Inspect and
replace parts as necessary.
If the actuator and valve are moving freely, reassemble the valve/actuator assembly and re-test. If unit still fails to

Maintenance
Actuators parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of
inspection and replacement depends upon the severity of service conditions. Instructions are given in subsequent
sections for disassembly and assembly of the actuator and for inspecting the actuator parts.
WARNING
Avoid personal injury from sudden release of process pressure. Before performing any maintenance operations:
D Do not remove the actuator from the valve while the valve is still pressurized.
D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
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 during maintenance.
D Use bypass valves or completely shut off the process pressure. Relieve process pressure on both sides of the valve. Drain
the process media from both sides of the valve.
D Vent the power actuator loading pressure and relieve any actuator spring precompression.
D Use lock-out procedures to be sure that the above measures stay in effect while you are work on the equipment.
D The valve packing area may contain process fluids that are pressurized, even when the valve has been removed from the
pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
Actuator Disassembly
Remove the actuator from the valve, and remove any other auxiliary equipment from the actuator. (Note the positions
of the mounting bracket and accessories for re-assembly). Steps explaining the disassembly and assembly of parts
apply to both ends of the actuator. If necessary, refer to the valve instruction manual for removing and replacing the
valve in the pipeline.
Key numbers are shown in figure 11 for E Series, and figure 12 for P Series actuators, unless otherwise noted.
CAUTION
Butterfly valves must be in the closed position before attempting to remove them from the pipeline. The valve disc can be
damaged if the disc is not moved to the closed position.
1. Remove the actuator mountingbracketandanyaccessories.
2. When removing the actuator end caps, carefully follow the steps below.
Operationally check the actuator to ensure that the pistons are moved all the way to the center (towards the drive
shaft), before removing the actuator end caps. Use the index mark on the top of the drive shaft (see figure 4).
a. For Double Acting E and P Series Actuators: Remove socket head screws from both end caps with a metric hex
key. After the screws are removed, gently pry off each end cap. Be careful not to damage the end cap sealing
surfaces.

b. For Spring Return E Series Actuators
It is very important to ensure that the springs are fully extended by retracting the piston (key 2) inwards toward the
drive shaft (key 3). Refer to figure 6.
WARNING
The pre-loaded spring pressure rests on the pistons when they are extended outward. If the end cap screws are removed
the spring loading is reduced, the end cap (key 5) can fly off the end of the actuator causing personal injury or
before
property damage.
Ensure that the pistons are moved fully toward the drive shaft. If this is not possible, provide a means of containing the end
capwhileremovingthesocketheadcapscrews.
The springs are retained within the end cap by the spring holder (key 9).
D Unscrew end cap socket head screws (key 36) a few turns
. Be sure the spring compression is resting on the socket
head cap screws. Equally release the spring compression while removing the socket head cap screws. The spring
precompression should be released before the screws are completely removed. Remove the spring cap assembly
from the actuator body.

c. For Spring Return P Series Actuators
It is very important to ensure that the springs are fully extended by retracting the piston (key 2) inwards toward the
drive shaft (key 3).
Operationally check the actuator to ensure that the pistons are moved all the way to the center (towards the drive
shaft), before removing the socket head cap screws (key 25, figure 12). Read the steps in this sub-section before
removing the end cap screws (key 25).
WARNING
The pre-loaded spring pressure rests on the pistons when they are extended outward. If the end cap screws are removed
the spring loading is reduced, the end cap (key 5) can fly off the end of the actuator causing personal injury or
before
property damage.
Ensure that the pistons are moved fully toward the drive shaft. If this is not possible, provide a means of containing the end
capwhileremovingthesocketheadcapscrews.
D Thespringsarein-betweentheendcapandpiston.Becarefulwhenremovingtheendcapasthespringsmayfall

D On a flat working surface, block-up the actuator so it is vertical to avoid the springs falling out of the actuator while
removing the end cap. Repeat on both ends of the actuator.
Note
If re-using springs, mark the springs and their location during disassembly. The springs must be replaced in the same location as
removed when re-assembling the actuator (see figure 9).
D Unscrew end cap socket head screws (key 25) a few turns. Be sure the spring compression is resting on the socket
head cap screws. Equally release the spring compression while removing the socket head cap screws. The spring
precompression should be released before the screws are completely removed. Remove the spring cap assembly
from the actuator body.
3. Clean, inspect, and/or obtain replacement parts. When reassembling the actuator, replace all soft parts provided in
the Parts Kits listed at the end of this manual.
4. Removetheadjustabletravelstop/housingadjustment(seefigure4).
5. Removing the Pistons: The two pistons (key 2) can now be removed by rotating the drive shaft, moving the piston
assemblies outward until the pinion gear has released them.
The gear rack in E Series actuators is machined into the piston, and so does not have to be removed separately. If the
gear rack is damaged, replace both pistons.
Removing the Drive Shaft
1. Remove the spring clip (E Series key 35, P Series key 20) with a pin spanner. Use caution, as the spring clip is under a
great deal of tension. Also, remove the E Series washers (keys 27 and 21) or P Series washer and O-ring (keys 21 and
19) from the shaft.
15
1035/El-O-Matic Actuator
August 2012
2. Remove the drive shaft (E Series key 3, P Series key 5, figures 11 and 12) through the bottom of the actuator.
3. For P Series actuators: remove the Piston Gear Rack. The gear rack in the P Series actuators is a separate part (key 6)
and is held in place with a socket head cap screw (key 22). Both gear racks can be removed and replaced by
removing them from the pistons.
4. Ensure that all actuator parts are clean and ready for assembly. Inspect the actuator body and component parts for
wear or scratches. If the inside wall of the body is scored the actuator will leak. Light traces of scoring, barely
detectable to the touch, are acceptable. Obtain replacement parts from your Emerson Process Management sales
office.

Actuator Assembly
Repair Kits
Repair kits are available for re-assembly. The large repair kit provides O-rings, guide bands, bushings, and bearings.
The small kit provides a set of soft parts only for the actuator. Repair kits are available for standard, low temperature,
and high temperature actuators. Refer to the Repair Kits table at the end of this manual.
Lubrication
Refer to the Specifications table for temperature ranges.
Standard and High Temperature Actuator: Lubricate the actuator moderately with a complex calcium sulphonate
grease suitable for the application's temperature range. Use the Parts Kit for the appropriate temperature application.
Low Temperature Actuator: Lubricate the actuator moderately with low temperature silicone grease. Use the Parts Kit
for standard and low temperature applications.
Lubricate the actuator moderately with an appropriate grease. Apply a light film of grease to all O-rings, gear racks,
bearings, bushings, and guide bands. In the following steps, lubricate all moving parts during re-assembly.
Installing the Drive Shaft
ESeriesactuators:Some constructions use a Dual Stop arrangement. The housing adjustment screw is used with a pin
located in the drive shaft, and a stroking adjustment cam mounted on the shaft for the stop. Ensure the cam is aligned
correctly with respect to the housing adjustment screw. Use figure 4 as a guide for alignment.
1. Replace the top and bottom shaft bearings (keys 20 and 12) in the actuator body.
2. Insert the adjustment screw, if applicable, and thread it into the body a few turns, and hand tighten the hex nut. The
adjustment screw should be loose enough to allow full travel of the cam and pistons.
3. Placethecam(seefigure4)onthesmallendofthedriveshaft.Positionthecamontheshaftsothepinislocatedin
the open section of the cam.
4. Install the O-rings and guide bushing on the drive shaft. The guide bushing may have to be cleaned of grease, rolled
tightly around the drive shaft and held in place while inserting into the actuator housing.
CAUTION
When inserting the drive shaft, be sure to keep the O-Rings from becoming trapped and damaged between the pinion and
the actuator body. To verify the condition of the O-Rings at the end of the installation, cycle the actuator 5 times and run a
soap bubble test on the seal on both the top and bottom of the drive shaft.
16
Instruction Manual
D500243X012
Note
Some constructions do not have a housing adjustment screw. If your construction does not use the adjustment screw, install the
drive shaft, and go to step 6 below.
1035/El-O-Matic Actuator
August 2012
5. Note the alignment of the cam with respect to the housing adjustment screw while installing the shaft into the
body. Install the drive shaft.
6. Install the washer, thrust washer, and spring clip (keys 27, 21 and 35) onto the drive shaft. Use the pin spanner
carefully to install the spring clip.
7. Go to the Installing Pistons steps below.
PSeriesActuators(without a 1080) use a Limit Stop Plate (see figure 4) for travel stops. The cam for the travel stops is
mounted on the actuator after the actuator is fully assembled.
1. Replace the top and bottom shaft bearings in the actuator body. Install the O-ring and guide bushing in the shaft.
The guide bushing may have to be cleaned of grease, rolled tightly around the drive shaft and held in place while
inserting into the actuator housing.
2. Insertthesmallendofthedriveshaft(key5) into the bottom of the actuator housing.
3. Install the thrust washer, and spring clip (keys 21 and 20) onto the drive shaft. Use the pin spanner carefully to
install the spring clip.
Installing Pistons
Figure7showsthealignmentoftheslotinthetopoftheshaftwiththepistonsforcodeAconstructions.Seefigure3
for piston and slot alignment for other constructions.
1. Install the O-ring and guide bushing on both pistons. For P Series actuators: you will need to install the gear racks on
the pistons if they were removed.
2. Lightly lubricate parts and inside of actuator bore before final assembly.
3. If you have not already done so, follow the steps in the Installing the Drive Shaft section.
4. Very carefully align the pistons square to the actuator housing.
5. Align the drive shaft so that the teeth on the center gear will “pick-up” the piston assembly rack teeth when turning
the top extension of the center gear clockwise.
To ensure proper meshing of teeth, rotate the index mark on the drive shaft 45 degrees beyond the open mark on the
top of the housing.
Note
Figure 3 shows the different orientation of the piston in relationship to the slot in the shaft, versus the actuator body.
6. With the piston assemblies in the actuator body, gently push them simultaneously into the housing. Turn the top
shaft extension clockwise. At the proper point of engagement between the center gear and piston assemblies, both
piston assemblies will move toward the center of the housing.
7. Once the drive shaft and pistons are properly engaged, ensure smooth movement at 90 degree operation can occur
without moving the pistons out of the actuator body. Do this by turning the top shaft extension to the closed
position and back a few times.

Spring Return E Series Actuators
Spring return E Series actuators use from two to a maximum of six springs. One, two, or three springs are inserted into
each end cap (see figure 8). R efer to the nameplate to verify the number of springs required.
Each end cap spring pack incorporates a travel stop adjustment screw (key 37). This may be used to adjust the end of
the stroke for valve seating in either the “fail open” or “fail closed” arrangements.
1. When installing used springs in a spring return actuator, ensure that the springs are replaced in the identical
position from which they were removed.
2. If a spring return actuator is being repaired due to spring failure, replace all the springs in the actuator.
3. To assemble the spring assembly, install the spring(s) into the end cap. Be sure that all springs are seated correctly
intheendcap(key5)andinthespringholder(key9).Placethespringholderandwasherontopofthesprings,and
install the adjustment screw (keys 34 and 37).
4. Place the end cap bolts through the retention holes of the end cap. If converting a double acting unit to a spring
return unit, be sure to use new end cap screws (key 25, figure 12).
5. Engage the bolts with the tapped holes in the actuator body by forcing down slightly on the cap. Tighten each bolt
in small, equal amount of turns, compressing the springs equally.
Spring Return P Series Actuators
Spring return actuators use from four to a maximum of fourteen springs. One through seven springs are inserted into
each end cap (see figure 9). R efer to the nameplate to verify the number of springs required.
1. When installing used springs in a spring return actuator, ensure that the springs are replaced in their identical
position in the end cap from where they were removed.
Note
When less than the standard number of seven springs are used in each end cap, the springs should be positioned as shown in
figure 9.
2. If a spring return actuator is being repaired due to a failed spring, replace all the springs in the actuator.
3. Ensure that the pistons are stroked fully inward, towards the center of the actuator (this may be done by rotating
the actuator shaft with a wrench).
4. When replacing the springs in a P Series spring-return actuator, position the actuator so that it stands on one end.
5. Place the springs on the piston face, engaging them with the alignment nibs cast into the piston.
6. Place the end cap over the springs. Align them with the corresponding nibs which are cast into the end cap.
7. If converting a double acting unit to a spring return unit, be sure to use new end cap screws (key 25, figure 12).
Install the end cap screws.
8. Engage the screws w ith the tapped holes in the actuator body by forcing down slightly on the cap. Tighten each
bolt in small, equal amount of turns, compressing the springs equally.
Installing the Bypass Valve
The optional bypass valve should be used when pressure needs to be stabilized between port A and port B (see figure
10). The following steps provide installation of the bypass valve. Removing the bypass valve simply requires
performing these steps in the reverse order.
20
Instruction Manual
D500243X012
1. Position the O-rings between the bypass block and the Namur mounting area. Attach the screws through the
bypass block to the Namur mounting area.
2. Attach the tubing to the fittings.
3. Attach the angle needle valve and the bypass block to the tubing.
4. Pressure the ports and check for leakage. Check the pressure to both ports A and B.
