For air‐to‐open actuator action only,
attach the pressure line to the actuator, and supply pressure to the actuator.
Loosen the socket head screws (key 29) and remove the flow adjuster (keys 14 and 15). Release the pressure to the
actuator. This allows the plug to find its seated position.
16. Set the flow adjuster to the desired travel position (see figure 2), and tighten the flow adjuster socket head cap
screws to 3 N
S
m (26 lbf

in).
17.
For air‐to‐close actuator action only,
attach a pressure line to the actuator. Supply pressure to the actuator to seat
the plug in the seat ring.
18. Set the flow adjuster to the desired travel position (see figure 2), and tighten the flow adjuster socket head cap
screws to 3 N
S

WARNING
Avoid personal injury from sudden release of process pressure. 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 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
on both sides of the valve. Drain the process media from both sides of the valve.
D
Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
Note
The NPT plug may be located in any port depending on customer installation requirements. The valve is shipped with the NPT plug
installed in the bottom port.
1. The NPT plug shall be inserted into the desired port using NPT pipe sealant and/or pipe tape.
2. Tighten the NPT fitting until hand tight, then add 1 to 2-1/2 turns 149 - 163 N•m (110 - 120 lbf•ft).
