Second, you will have to fabricate a custom mounting bracket and coupling to connect the actuator to the valve. T he valve will stop somewhere between full open and close. When power is reapplied to the original circuit, the actuator will complete the cycle. I ordered a fail open pneumatic actuated valve by mistake. I needed a fail closed one.
R emove the actuator from the valve and check the valve stem.
Most ball valves have stem flats at right angles to the flow when the valve is in the off position. On butterfly valves check the stem flow arrow marking. N o, a remote location is fine. Just make sure that the air pressure at the actuator is sufficient to power it. The air pressure at the actuator may be less than the pressure at the remote solenoid, be sure to check it.
