Installation
The valve is normally shipped as part of a control valve assembly, with the power actuator mounted on the valve. If the
valve or actuator have been purchased separately, or if the actuator has been removed for maintenance, mount the
actuator on the valve, and adjust actuator travel before inserting the valve body into the line. This is necessary due to
the measurements that must be made during the actuator calibration adjustment process. Refer to the Actuator
Mounting section of this manual to mount the actuator on the valve. Refer to the actuator instruction manual for
mounting and adjusting instructions before proceeding.
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the valve
assembly where service conditions could exceed the limits given in this manual, the limits on the appropriate nameplates,
or the matching pipe flange rating. Use pressure‐relieving devices as required by government or accepted industry codes
and good engineering practices.
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.
WARNING
The valve configuration and construction materials are selected to meet particular pressure, temperature, pressure drop,
and controlled fluid conditions. Responsibility for the safety of process media and compatibility of valve materials with
process media rests solely with the purchaser and end‐user. Since some valve body/trim material combinations are limited
in their pressure drop and temperature range capabilities, do not apply any other conditions to the valve without first
contacting your Emerson sales office

Valve Orientation
When installing the valve, it is recommended that the valve drive shaft be horizontal as shown in figure 1.
Note
Due to its weight, the 1052 size 70 actuator must be externally supported when mounted in a horizontal position.
Valve Direction
The high performance butterfly valve is designed to allow flow in either direction when in the open position. When in
the closed position, high pressure should be applied to a specific side of the disk to provide best performance and
optimal valve life (see list of seal types below). See figure 3.
Applications with bi‐directional seals, such as soft or Phoenix III, under normal operating conditions can (at different
times) experience pressure in both directions; the highest of the two pressures should be exerted on the preferred side
of the disk. If the two pressures are equal, then the one lasting the longest period of time should be applied to the
preferred side.
1. For PTFE, Reinforced PTFE, and UHMWPE seal rings: This seal is bidirectional. For optimal performance, high
pressure should be applied to the front (retaining ring side) of the disk.
2. For metal seal rings:
a. NOVEX seal: The NOVEX seal is uni‐directional. High pressure at the closed position MUST be at the back
(waterway side) of the disk.
b. Phoenix III Seal: This seal is bidirectional. For best performance, high pressure at the closed position should be
applied to the back (waterway side) of the disk.
c. NPS 2 Seal: The preferred direction of installation is with high pressure at the front (retaining ring side) of the
disk. Reverse shutoff is permissible at lower pressure (see the specifications table).

Installing the Valve in the Pipeline
WARNING
The edges of a rotating disk have a shearing effect that may result in personal injury. To help prevent such injury, stay clear
of the disk edges when rotating the disk (key 3, figure 14).
CAUTION
Damage to the disk will occur if any pipe flanges or piping connected to the valve interfere with the disk rotation path. If
the piping flange has a smaller inner diameter than what is specified for schedule 80 piping, measure carefully to be certain
the disk rotates without interference before putting the valve into operation.
CAUTION
Damage to the disk (key 3) sealing surfaces may occur if the disk is not closed when the valve is being removed from the
pipeline. If necessary, use a temporary pressure source on the actuator to retain the disk in the closed position while
removing the valve from the pipeline.

8560 Valve
February 2019
Instruction Manual
D102013X012
1. For Fail‐Open Actuators: It will be necessary to provide a temporary loading pressure to the actuator diaphragm to
move the valve disk to the closed position. Observe the above Warning when closing the valve. If a loading pressure
is required, use caution when working with the valve. If the loading pressure is disconnected, the disk will open
rapidly.
2. With the disk in the closed position, install line flange gaskets, and install the valve between the pipeline flanges.
WARNING
If spiral wound gaskets are to be used with an NPS 3 or 4 CL150 or 300 single flange valve, special spiral wound gaskets
conforming to the dimensions listed in the table 5 MUST be used. Improperly sized gaskets may increase the likelihood of 1)
excessive seat leakage, 2) damage due to contact with valve internals, and 3) external leakage; which may result in personal
injury and/or property damage due to a sudden increase or decrease of pressure within
pipeline. The special dimension spiral wound gaskets can be obtained from your local spiral wound gasket vendor.
Note
The remaining single flange valve sizes (NPS 6 through 12) and all wafer style valves (NPS 2 through 12) use the standard size spiral
wound gaskets. Only the single flange valves in the sizes and pressures listed in table 5 require special spiral wound gaskets.
‐ or release of pressure from ‐ the
Select the appropriate gaskets for the application. Flat sheet, spiral wound (NPS 6 through 12), or other gasket types
made to ASME 16.5 group or a user's standards can be used for 8560 valves depending on the service conditions and
applications.
3. Install the flange studs:
Note
Lubricate line flange studs or bolts before inserting them into flanges. If necessary, provide additional support for the control valve
assembly because of its combined weight.
D Flange studs: Install two or more line flange studs into the line flanges to help hold the valve in position while
centering the valve. Carefully center the valve on the flanges to ensure disk clearance.

D Select and install two pipe line gaskets.
D Flange Cap Screws: If line flange cap screws are used, be certain the cap screw threads engage the tapped holes to a
depth equal to the flange cap screw diameter.
4. Install the remaining line flange bolting to secure the valve in the pipeline. Tighten the nuts to the line flange studs,
or cap screws, in a crisscross pattern to ensure proper alignment of valve, gaskets, and flanges.
Packing Adjustment and Shaft Bonding
WARNING
Personal injury could result from packing leakage. Valve packing was tightened before shipment; however the packing
might require some readjustment to meet specific service conditions. Check with your process or safety engineer for any
additional measures that must be taken to protect against process media.
CAUTION
Use caution when tightening packing follower nuts because over‐tightening the nuts will accelerate wear and could
produce higher rotating friction loads on the valve stem.
1. For PTFE or graphite packing: tighten standard packing follower nuts only enough to prevent shaft leakage.
Excessive tightening of packing will accelerate wear and could produce higher rotating friction loads on the valve
stem. If necessary, refer to the Packing Maintenance section.
2. ENVIRO‐SEAL Packing System will not require this initial re‐adjustment. Refer to the separate ENVIRO‐SEAL Packing
System for Rotary Valves instruction manual (D101643X012) for repair and replacement procedures.
3. For hazardous atmosphere or oxygen service valves, read the following Warning, and provide the bonding strap
assembly mentioned below if the valve is used in an explosive atmosphere.
WARNING
The valve drive shaft is not necessarily grounded to the pipeline when installed. Personal injury or property damage could
result from an explosion caused by a discharge of static electricity from the valve components if the process fluid or the
atmosphere around the valve is flammable. To avoid personal injury or property damage, make sure the valve is grounded
to the pipeline before placing the valve assembly into service.
Standard PTFE packing is composed of a partially conductive carbon‐filled PTFE female adaptor with PTFE V‐ring packing.
Standard graphite packing is composed of all conductive graphite ribbon packing rings. Alternate shaft‐to‐valve body
bonding is available for hazardous service areas where the standard packing is not sufficient to bond the shaft to the valve
(see the following step).
For oxygen service applications it is necessary to provide alternate shaft‐to‐valve body bonding according to the following
step.
4. Attach the bonding strap assembly (key 131, figure 5) to the shaft with the clamp (key 130, figure 5), and connect
the other end of the bonding strap assembly to the valve with the cap screw (key 22, figure 5).
5. For more information, refer to the Packing Maintenance subsection below.
Maintenance
Valve 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 this section for replacing
9
8560 Valve

Instruction Manual
D102013X012
packing, seal ring, disk, shaft, bearings, and other valve parts. Also, instructions are provided for changing valve action,
mounting, and adjusting the actuator. Refer to the actuator instruction manual for additional information for
mounting and adjusting the actuator.
CAUTION
It is possible to damage the valve if the actuator travel stops are not properly adjusted before stroking the valve.
WARNING
Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. 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, electric power, 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
from both sides of the valve. Drain the process media from both sides of the valve.
D Vent the pneumatic 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 work on the equipment.
D The valve packing box 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, or when
loosening the packing box pipe plug.
D The edges of a rotating disk have a shearing effect that may result in personal injury. To help prevent such injury, stay
clear of the disk edges when rotating the disk (key 3).
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
CAUTION
During any of the following steps, do not rotate the disk past 90 degrees in the open direction. Rotating the disk past 90
degrees can damage the seal ring.
Stopping Leakage
For PTFE‐filled or graphite standard packing arrangements covered in this manual, often leakage from the packing can
be stopped by tightening the packing flange nuts just enough to stop the leak.
CAUTION
Use caution when tightening the nuts because over‐tightening the nuts can damage packing box parts.
10
Instruction Manual
D102013X012
8560 Valve
February 2019
D If tightening the packing flange nuts does not stop the leakage, use the following procedures to remove the control
valve assembly from the pipeline. Remove the actuator when removing and replacing packing parts.
D If the leakage comes from the outside diameter of the packing box, it is possible that the leakage is caused by nicks
or scratches on the packing box wall. Carefully inspect the packing box bore and valve drive shaft when the packing
is removed. Use the following steps to remove the actuator and to remove and replace the packing parts.
Removing the Actuator
1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the
process media from both sides of the valve. If using a power actuator, also shut off all pressure lines to the power
actuator, and release all pressure from the actuator. Use lock‐out procedures to be sure that the above measures
stay in effect while you work on the equipment.
CAUTION
Damage to the disk (key 3) sealing surfaces may occur if the disk is not closed when the valve is being removed from the
pipeline. If necessary to overcome spring force, use a temporary pressure source on the actuator to close the disk. Also,
maintain the pressure to retain the disk in the closed position while removing the valve from the pipeline.
2. Be sure the disk is in the closed position before attempting to remove the valve from the pipeline or flanges.
WARNING
The edges of a rotating disk close with a shearing effect that may result in personal injury. To help prevent such injury, stay
clear of the disk edges when rotating the disk (key 3).
For Fail‐Open Actuators: It will be necessary to provide a temporary loading pressure to the actuator diaphragm to
move the valve disk to the closed position. Observe the above Warning when closing the valve. If a loading pressure is
required, use caution when working with the valve. If the loading pressure is disconnected, the disk will open rapidly.

3. With the disk in the closed position, remove line bolting, remove the control valve assembly from the pipeline, and
place it on a flat working surface with the seal retainer ring facing up.
4. If a grounding strap is used (see figure 5), remove the hex nut to release the end of the strap. Remove the clamp
(key 130) and strap (key 131).
5. Note the orientation of the actuator with respect to the valve body (see figure 6), and remove the actuator cover to
note the lever orientation with respect to the valve drive shaft (see figure 7).
When re‐assembling the control valve assembly, you will need to correctly position the marks on the end of the valve
drive shaft and the valve body with respect to the actuator case and lever arm. Refer to the Actuator Mounting section
and figure 7 for the location of the marks on the valve drive shaft end. Additional information is provided in the
actuator manual to assist with disassembly, re‐assembly, and travel adjustments. When removing the valve drive shaft
from the actuator lever, do not loosen the actuator turnbuckle adjustment. Remove the cap screw from the actuator
lever (figure 7).

D102013X012
CAUTION
When removing the actuator from the valve, do not use a hammer or similar tool to drive the actuator lever off the valve
shaft. Driving the lever off the valve shaft could damage the disk, seal ring, bearings or valve body.
If necessary, use a wheel puller to remove the actuator lever from the valve shaft. It is okay to tap the wheel puller screw
lightly to loosen the lever, but hitting the screw with excessive force could damage the disk, seal ring, bearings or valve
body.
6. Remove the actuator mounting screws (key 14, figure 14).
7. Remove the valve from the actuator.
Packing Maintenance
Standard graphite packing is composed of all conductive packing rings. PTFE‐filled packing has a partially conductive
packing ring (such as a carbon‐filled PTFE female adaptor) to electrically bond the shaft to the valve body.
If the valve is equipped with the optional ENVIRO‐SEAL Packing System, refer to the separate ENVIRO‐SEAL Packing
System for Rotary Valves instruction manual (D101643X012
When replacing the packing, it is recommended to remove the control valve assembly from the pipeline because
valve/actuator adjustments must be made with the valve out of the pipeline.
Disassembly
Key numbers and part locations are shown in figure 8 unless otherwise noted.
1. Remove the packing flange nuts (key 101 ) and the packing flange (key 102).
2. Remove the old packing rings, using a formed hook.
CAUTION
Carefully use the hook. Avoid damaging the drive shaft or packing box wall. Scratches on valve surfaces can cause leakage.
(Note: the packing box ring (Key 107) can remain in place when replacing packing only.)
) for packing maintenance procedures.
3. Clean all accessible metal parts and surfaces to remove particles that would prevent the packing from sealing.

Inspect the shaft: If it is damaged, it cannot make a good seal with the packing, and it must be replaced. If the leakage
comes from the outside diameter of the packing, it is possible that the leakage is caused by nicks or scratches around
the packing box wall. Inspect the packing box wall for nicks and scratches when performing the following procedures.
If the valve is equipped with the ENVIRO‐SEAL packing system refer to the ENVIRO‐SEAL Packing System for Rotary
Valves instruction manual for assembly.
Note
Except with oxygen service, lightly lubricate new PTFE V‐rings with a silicone‐base lubricant to aid in assembly.
WARNING
Do not lubricate parts when used in oxygen service, or where the lubrication is incompatible with the process media. Any
use of lubricant can lead to the sudden explosion of media due to the oil/oxygen mixture, causing personal injury or
property damage.

1. Install the new packing parts (see figure 8). Install the packing follower and finger tighten the packing flange nuts
onto the studs only enough to stop leakage.
2. If the valve was equipped with a bonding strap assembly (figure 5), re‐install the assembly.
3. Refer to the Actuator Mounting section of this manual. If necessary, refer to the separate actuator instruction
manual for adjustment procedures.
4. When the control valve is being placed into operation, check around the packing follower for leakage.
For PTFE‐filled or graphite standard packing arrangements covered in this manual, leakage from the packing can often
be stopped by tightening the packing flange nuts just enough to stop the leak.
CAUTION
Use caution when tightening the nuts. Overtightening the nuts can damage packing box parts and result in increased drive
shaft friction.
Seal Ring Maintenance for NPS 3 through 12
Perform this procedure if the control valve is not shutting‐off properly (if it is leaking downstream). It is recommended,
but not required, to remove the actuator for easier handling of the valve during the following procedures.
CAUTION
During any of the following steps, do not rotate the disk past 90 degrees in the open direction. Rotating the disk past 90
degrees can damage the seal ring.

1. Remove the retainer ring (key 2, figure 10):
For valves with press‐fit retainer rings:
D Place the valve on blocks with the seal retainer facing down. (Note: Position blocks so they do not restrict the
retainer ring removal.)
D Rotate the disk to the open position as shown in figure 9.
D Locate one of the knock‐out points machined on the retainer ring. Using a hammer and flat end punch on the
knock‐out point, pop out the retainer ring from the valve body.
CAUTION
When popping out the retainer ring, be very careful to hit only the knock‐out points. Hitting anywhere else can cause
non‐repairable damage to the t‐slot area.
D Clean all sealing surfaces and parts before re‐assembly.
For valves with screwed retainer rings
D Place the valve on blocks with the seal retainer facing up
.
D Remove the retainer ring screws (key 17). If necessary, use two of the retainer screws in the tapped holes in the
retainer ring (key 2, figure 14) to jack the retainer ring loose from the valve body surface.
2. Remove the seal ring from the valve body seal ring slot.
For valves with PTFE seal rings, remove the spring (key 5) as it may be necessary to re‐install the spring into the new
PTFE seal ring.
For valves with metal seals, remove the gasket (key 16) from the valve body surface, and discard it as replacement is
recommended.
3. If it is necessary to replace the disk, drive shaft, and the bearings, refer to that section below before proceeding with
the assembly procedures for the seal ring and retainer. The seal ring could be damaged if it is in place while
removing the disk.
Assembly
Place the valve on blocks with the seal retainer facing up. If the replacement disk, shaft, and bearings have not been
installed in the valve body, go to the proper assembly procedures to install them.
CAUTION
Do not install the seal ring without the disk being in place. The seal ring could be damaged while installing the disk.
WARNING
Do not lubricate parts when used in oxygen service, or where the lubrication is incompatible with the process media. Any

2. Installing metal seals:
Note
For metal seals only, it may be necessary to apply a dry film lubricant or equivalent moly disulfide to the sealing surfaces of the
disk, seal and the seal retainer groove. Prior to applying the lubricant the sealing surfaces should be inspected for injurious defects.
Surfaces can be polished using a scuffing hand pad or equivalent. The edge of the seal that contacts the retaining ring groove
should also be inspected and polished if necessary.
Note
Use the appropriate lubrication on parts when used in oxygen service, or where the lubrication is incompatible with the process
media.
a. Rotate the disk to the open position as shown in figure 10.
19

CAUTION
The seal ring will be damaged if the disk remains in the closed position during seal and retainer ring assembly.
b. Install the metal seal ring assembly (see figure 11).
3. Installing the retainer ring:
a. Valves with PTFE seal rings do not require a retainer ring gasket (key 16).
b. Valves with metal seals require a retainer ring gasket (key 16).
CAUTION
When handling the new retainer ring gasket, be sure to avoid kinking, cracking, or breaking the gasket. Damage to the
gasket can cause leakage between the seal retainer and valve body.
c. Lay the gasket (key 16) down so that it is accurately centered on the valve body.
4. For valves with press‐fit retainer rings
a. Wipe excessive oil off the retainer ring outside diameter, and off the retainer counterbore in the valve body.
b. Rotate the disk to the open position.
c. Lay the retainer ring on the valve body.
d. Use a press, or a soft‐faced hammer to press the retainer ring into its groove in the valve body.
CAUTION
It takes a considerable amount of force with a hammer to drive the retainer ring into place. Be sure not to damage retainer
ring surfaces when installing the ring.
e. The retainer ring is properly seated when the face of the retainer ring is flush with the face of the valve body.
f. To ensure proper seal performance for metal seals, you may need to use the hammer to drive the disk open for
the first few times. When closing the valve, use the C‐clamps discussed in the next few steps.
CAUTION
Do not damage the gasket seating surfaces on either the valve body or the retainer ring when installing or removing the
C‐clamps. Protect the gasket surface by using a soft material between the clamp and valve body/retaining ring serrations
to avoid damage.
20
Instruction Manual
D102013X012
g. Use three C‐clamps to hold the retainer in place. Locate one of the C‐clamps near the travel stop in the valve
body, and the other two at 120 degrees from the stop.
h. When cycling the disk for the first three times, use a dead‐blow hammer with a soft head to drive the disk closed.
Also, you may need to use the hammer to drive the disk open for the first few times.
5. For valves with screwed retainer rings
a. Match the retainer ring with the holes in the valve by punching two holes in the gasket to locate where the screw
holes are in the valve.
b. Lay the retainer ring over the gasket, while lining it up with the punched holes. Also insert two retainer screws
(key 17). Finger tighten them.
c. Press the remaining screws through the gasket material and finger tighten them. When all retainer screws are in
place, tighten them in a crisscross pattern.
d. The retainer ring is properly seated when the retainer face is nearly flush with the face of the valve.
6. Turn the disk into and out of the seal ring several times, to help break in the seal and reduce actuator torque
requirements during adjustment.
7. If replacing the packing, remove all packing parts from the valve body. Upon re‐assembly of the valve, refer to the
Packing Maintenance procedures to replace the packing.
8560 Valve

Seal Ring Maintenance for NPS 2
This procedure is to be performed if the control valve is not shutting off properly (that is, leaking downstream). This
procedure does not require removing the actuator from the valve body. Part key numbers are shown in figure 15.
WARNING
Refer to the WARNING at the beginning of the Maintenance section in this instruction manual.
1. Isolate the control valve from line pressure, and relieve pressure from the valve body. Shut off and disconnect all
lines from the power actuator.
WARNING
The edges of a rotating disk have a shearing effect that may result in personal injury. To help prevent such injury, stay clear
of the disk edges when rotating the disk (key 3).
CAUTION
Damage to the disk (key 3) may occur if the disk is not closed when the valve is being removed from the pipeline. If
necessary, pressure the actuator temporarily to retain the disk in the closed position while removing the valve from the
pipeline.
2. Unscrew the flange bolts, and remove the valve from the pipeline.
21
8560 Valve
February 2019
3. Unscrew the machine screws (key 17), and remove the seal retainer (key 2). Also remove the retainer clip (key 30).
4. Remove the seal ring or seal ring assembly(key 4). The spring (key 5) is removed with a PTFE seal ring.
5. For 316 stainless steel seal ring assemblies, replace the gaskets (key 4C) if the entire seal ring assembly is not
replaced. Scrape off the old gaskets from both sides of the seal ring and the seal ring sides of the valve body (key 1)
and seal retainer. Clean the gasket surfaces.
6. Reconnect or mount the actuator (if it was removed) before proceeding.
For an actuator with adjustable travel, also adjust the actuator before proceeding. This is necessary due to the
measurements that must be made during the actuator adjustment process.
Refer to the Actuator Mounting section of this manual and to the separate actuator instruction manual for mounting
and adjusting instructions.
7. The valve should be closed during seal ring installation to permit accurate centering of the seal. To install the new
seal ring:
For a PTFE seal, if the spring (key 5) was disassembled, hook the spring ends together. Work the spring into the recess
in the seal ring (key 4). Install the seal ring and spring assembly into the recess in the valve body as shown in figure 15.
For a complete 316 stainless steel seal ring assembly, install the seal ring assembly as shown in figure 15.
Instruction Manual
D102013X012
CAUTION
New seal ring gaskets (key 4C) are very fragile and must be handled very carefully to avoid gasket kinking, cracking, or
breakage that can cause leakage between the seal ring, seal retainer, and valve body. To avoid gasket damage, make sure
that the valve body is lying flat so that the gaskets do not shift before the following steps are completed.
8. For a 316 stainless steel seal ring on which the gaskets will be replaced, lay the following parts down in order so that
they are accurately centered on the valve body: one new gasket; the seal ring oriented as shown in figure 15; and
the second new gasket.
9. Attach the seal retainer and, if used, the retainer clips and washers to the valve body and secure with the machine
screws. Tighten the machine screws evenly so as not to crack or break the 316 stainless steel seal ring gaskets, if
used.
Be certain the disk is closed before installing the valve according to the Installation section of this instruction manual.

Disk, Shaft Assembly and Bearing Maintenance for NPS 2
This procedure is to be performed to replace the valve disk, shaft, and taper pin assembly if the disk does not rotate in
response to rotation of the actuator end of the valve shaft. Unless otherwise indicated, part key numbers are shown in
figure 15.
Disassembly
1. Remove the seal ring according to steps 1 through 5 of the Replacing Seal Ring section.
CAUTION
Use a wheel puller to separate actuator parts from the valve shaft. Driving the parts off the valve shaft could move the valve
bearings and disk away from the centered position, damaging the disk and valve body.
2. Remove the cap screws and, if used, the hex nuts. Remove the clamp if the strap is used. Remove the actuator from
the valve body while referring to the separate actuator instruction manual for assistance.
3. Rotate the disk (key 3) to the fully open position.
4. Locate the half of the disk that has two C markings cast into it as shown in figure 10. Drive the two taper pins (key
3C) out toward the C‐marked side of the disk. Attempting to drive the taper pins in the opposite direction only
tightens the pins.
5. Unscrew and remove the packing flange nuts (key 101), packing followers (key 114), and packing flanges (key 102)
if used, from both sides of the valve.
WARNING
Once the shaft has been removed in the following step, the disk may fall from the valve. To avoid personal injury and disk
damage, support the disk to prevent it from falling as the shaft is being removed.
6. Pull the shaft out through the actuator side of the valve.
7. Remove the disk from the valve body.
8. Remove the packing rings (key 108), the packing washers (key 115) if used, and the packing box ring (key 107).
25
8560 Valve
February 2019
Instruction Manual
D102013X012
9. If either of the bearings (key 6) require maintenance or replacement, remove them.
CAUTION
When replacing a valve disk or shaft, a new disk/shaft/taper pin assembly (key 3) should be used. Using a new disk with a
used shaft requires drilling and reaming new taper pin holes in the shaft. The extra set of taper pin holes weakens the shaft
and may cause it to fail in service.
10. Clean the packing boxes and metal packing box parts.
Assembly
1. Drop in the new bearings. Make sure to orient the tab in the bearing with the slot in the seal.
2. Insert the disk into the valve body. Be certain the taper pin holes in the disk are on the actuator side of the valve.
Also be certain the letter C stamped on either face of the disk is on the same side of the valve as the letter C
stamped on the outside of the valve (figure 10).
3. Slide the shaft through the valve body and disk.
4. Install the disk and spacers into the valve body. Insert the shaft into the valve body and through the disk.
5. Slide the shaft all the way into the valve body.
6. To ensure that the direction of taper in the shaft taper pin holes matches that of the disk taper pin holes,
temporarily install the packing follower (key 114) or, if used, the packing flange (key 102) with rotation tag (key 19).
With the disk fully opened, rotate the shaft until the line on the end of the shaft indicates the open position, as
shown in figure 10. Insert the taper pins (key 3C), small end first, into the taper pin holes on the C‐marked side of
the disk. Do not drive in the pins. Remove the packing follower or flange.
Actuator Mounting
Re‐install the seal ring and packing rings using the appropriate procedures before installing the actuator on the valve.
Mount the actuator on the valve body in accordance with the instructions in the actuator instruction manual and this
section.
In the Packing Maintenance/Removing the Actuator steps, you should have noted the position of the mark on the end
of the valve shaft, and its relationship to the actuator shaft. If not, determine the configuration needed to match your
application.
Be certain that the disk is rotating counterclockwise to open when viewed from the actuator side of the valve, and that
the disk is not rotated beyond its limits.
1. Orientate the valve drive shaft correctly to match the actuator or handlever position, and install it into the actuator
and actuator lever arm until the mounting pads mate with each other.
2. Tighten the actuator‐mounting cap screws (key 14, figure 14) to the appropriate bolt torque from table 7.
CAUTION
The valve disk stop, in the valve body bore is not to be used as a power actuator travel stop (see figure 9). Use the actuator
travel stops to limit the rotation of the valve disk. It is possible to damage the valve component parts if full actuator thrust
is applied to the valve disk stop.
For actuators with an adjustable turnbuckle, such as the 1051, 1052, or 1061 actuator, the turnbuckle must be adjusted so
that the valve is closed (determined by measuring as shown in figure 7) when the diaphragm or piston is against the
actuator travel stop.
For manually operated actuators or actuators without adjustable linkage, such as the 1066 or 1066SR actuator, make
certain that the travel of the actuator stops before the disk rotates past the closed position.

Note
To obtain proper shutoff, the closed position of the A41/8560 valves must be set with the disk parallel to the retaining ring. Don't
use the disk stop to set the actuator travel stops.
3. Adjust the actuator travel stop to limit the open and closed positions of the valve disk. (If necessary, refer to the
actuator instruction manual for more information about adjustments.) Do not use the disk stop as a actuator travel
stop as discussed in the Caution above.
4. For actuators with adjustable turnbuckles, adjust the turnbuckle to bring the disk to the fully closed position at the
end of the actuator stroke. If necessary, refer to the appropriate actuator instruction manual for assistance.
5. If using a manual handwheel or handlever actuator, refer to the appropriate actuator instruction manual for
mounting positions and adjustments.
6. To determine the fully closed disk position (zero degrees of disk rotation), measure the distances between the
positions on the disk face as shown in figure 10. Use the actuator to rotate the disk while re‐checking the two
measurements. Repeat adjustment until the two measurements are equal.
