With the pointer (key 42) in the neutral position, automatic operation is possible throughout full travel. The locking
pin (key 10) should be left out during automatic operation, and the needle valve (key 54) must be closed.
For manual operation, the locking pin (key 10) must be inserted into the hole in the sleeve assembly before you open
the needle valve (key 54). Rotation of the handwheel (key 32) in either direction causes the valve stem to move
because of the pinned connection between the piston rod extension and sleeve. There is a directional arrow and the
word “OPEN” cast on the handwheel to indicate the rotation required to open the valve. To shift from manual to
automatic operation, return the handwheel pointer (key 42) to the neutral position, close the needle valve (key 54),
and remove the tapered pin (key 10).
The handwheel assembly can provide a travel stop to restrict upward travel of the valve plug. When you set the travel
stop, the tapered pin (key 10) should be left out. As an example, consider the control valve with a push-down-to-close
valve plug action. To restrict full opening, turn the handwheel (key 32) to lower the sleeve assembly (key 9). In normal
operation, as the valve opens, the stem connector (key 22) contacts the lower part of the sleeve before full valve travel
is reached. You can note the amount of restriction on the travel scale (key 7).
Note
If an emergency arises, you can close the valve (push-down-to-close) quickly without inserting the pin into the sleeve assembly.
First, turn the handwheel to move the sleeve against the stem connector (key 22), then open the needle valve and turn the
handwheel to force the valve plug closed.
Maintenance
Instructions are given below for complete disassembly of the actuator. When inspection or repair is necessary,
disassemble the actuator only as far as is required to accomplish the job.
WARNING
Avoid personal injury from sudden release of process pressure or uncontrolled process fluid. Before starting disassembly:
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 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
on both sides of the valve. Drain the process media from both sides of the valve.
D
Vent the power actuator loading pressure.
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
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
