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.
