Maintenance

Use table 4 to locate and correct possible leakage or mechanical linkage problems with the valve.

WARNING

Avoid personal injury from sudden release of process pressure. Before performing any maintenance operations:

DAlways wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal injury.

DDisconnect 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.

DUse 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.

DVent the power actuator loading pressure and relieve any actuator spring precompression.

DUse lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.

DThe 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.

DCheck with your process or safety engineer for any additional measures that must be taken to protect against process media.

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.

Disassembly

Key numbers locations are shown in figure 7.

1.Loosen all flange studs or bolts. Remove all but the bottom flange studs or bolts.

CAUTION

To avoid damage to the valve disc caused by the disc hitting the mating flange, be certain the disc is closed before removing the valve from the pipeline.

2.If necessary, pry flanges apart so that liner faces will not be damaged when the valve is being removed. Inspect the disc (key 3) and liner (key 2) for wear or damage.

3.Remove the actuator from the valve. Follow instructions in the appropriate actuator instruction manual.

4.From both sides of valve, unscrew thrust-plate cap screws (key 10) and remove thrust plates (key 9).
