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 or Local Business Partner.

A6306-2
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 disc 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 disc. 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 disc.
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 disc.
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 disc.
c. NPS 2 Seal: The preferred direction of installation is with high pressure at the front (retaining ring side) of the
disc. Reverse shutoff is permissible at lower pressure (see the specifications table).

Installing the Valve in the Pipeline
WARNING
The edges of a rotating disc have a shearing effect that may result in personal injury. To help prevent such injury, stay clear
of the disc edges when rotating the disc (key 3, figure 14).
CAUTION
Damage to the disc will occur if any pipe flanges or piping connected to the valve interfere with the disc 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
disc rotates without interference before putting the valve into operation.
CAUTION
Damage to the disc (key 3) sealing surfaces may occur if the disc 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 disc in the closed position while
removing the valve from the pipeline.

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 disc 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 disc will open
rapidly.
2. With the disc 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 ‐ or release of pressure from ‐ the
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.
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 disc 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

Instruction Manual
D102013X012
8560 Valve

packing, seal ring, disc, 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 disc have a shearing effect that may result in personal injury. To help prevent such injury, stay
clear of the disc edges when rotating the disc (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 disc past 90 degrees in the open direction. Rotating the disc 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.

Instruction Manual
D102013X012
8560 Valve
June 2017
11
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 disc (key 3) sealing surfaces may occur if the disc 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 disc. Also,
maintain the pressure to retain the disc in the closed position while removing the valve from the pipeline.
2. Be sure the disc is in the closed position before attempting to remove the valve from the pipeline or flanges.
WARNING
The edges of a rotating disc close with a shearing effect that may result in personal injury. To help prevent such injury, stay
clear of the disc edges when rotating the disc (key 3).
For Fail‐Open Actuators: It will be necessary to provide a temporary loading pressure to the actuator diaphragm to
move the valve disc 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 disc will open rapidly.

3. With the disc 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).
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 disc, 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 disc, 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) for packing maintenance procedures.
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.)
3. Clean all accessible metal parts and surfaces to remove particles that would prevent the packing from sealing.

Assembly
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 disc past 90 degrees in the open direction. Rotating the disc 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 disc 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 disc, 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 disc.
Assembly
Place the valve on blocks with the seal retainer facing up. If the replacement disc, 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 disc being in place. The seal ring could be damaged while installing the disc.
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.

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
disc, 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 disc to the open position as shown in figure 10.

CAUTION
The seal ring will be damaged if the disc 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 disc 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 disc 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.
