Question 1

The actuator on my automated valve operates, but the valve won’t turn. Why?

Accepted Answer

Most likely the valve stem or actuator coupling is broken.

Question 2

Why doesn’t my valve open or close completely when the actuator operates it?

Accepted Answer

The electric actuator limit switches or the pneumatic actuator position stops are not correctly adjusted.

Question 3

When I energize the solenoid on my pneumatic actuated valve, the valve won’t turn. How come?

Accepted Answer

Probably because there is no air pressure to the solenoid or dirt has jammed it. Also, debris might be trapped inside the valve. Or, the air pressure is not sufficient to operate the actuator. Remember: measure air pressure at the actuator, not at the compressor.

Question 4

Can I buy an actuator from one manufacturer and mount it to a valve from another manufacturer?

Accepted Answer

Maybe. First, be sure that the actuator torque output is sufficient to turn the valve reliably. Second, you will have to fabricate a custom mounting bracket and coupling to connect the actuator to the valve.

Question 5

What happens if I lose power to my electric actuator in the middle of an actuation cycle?

Accepted Answer

The valve will stop somewhere between full open and close. When power is reapplied to the original circuit, the actuator will complete the cycle.

Question 6

I ordered a fail open pneumatic actuated valve by mistake. I needed a fail closed one. What can I do?

Accepted Answer

To make the change just remove the actuator from the valve and turn it, or the valve stem, 90 degrees and remount the actuator.

Question 7

I’ve installed my automated valve in the line, but now I don’t know if the valve is in the open or closed position. How can I find out?

Accepted Answer

Remove 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.

Question 8

Do I have to have the solenoid valve that controls the air supply to my pneumatic actuator mounted right on the actuator?

Accepted Answer

Remove 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.

Question 9

How do I wire up my electric actuator?

Accepted Answer

Check the electric wiring schematic that came with the actuator for the correct hookup. Sometimes a copy is inside the actuator cover. If it is missing, don’t guess about the connections. Call the manufacturer for a schematic.

Question 10

I’ve just installed an electric actuated valve and when I power it, it turns the valve 360 degrees and won’t shut off. What’s wrong?

Accepted Answer

The actuator is wired incorrectly (check the schematic accompanying the actuator), or the external control switch is not the correct type for the actuator.

Question 11

My electric actuators cycle time is way too fast, can I slow it down?

Accepted Answer

Not unless you bought it with an optional speed control.

Question 12

I just replaced a solenoid valve with an electric actuated valve and it won’t work. Why?

Accepted Answer

Actuators and solenoid valves require different types of electrical control switches. SPDT for actuators, SPST for solenoids. Check the actuator wiring schematic for the correct wiring and switch type.
