Q: The actuator on my automated valve operates, but the valve won’t turn. Why? A: Most likely the valve stem or actuator coupling is broken.
Q: Why doesn’t my valve open or close completely when the actuator operates it? A: The electric actuator limit switches or the pneumatic actuator position stops are not correctly adjusted.
Q: I ordered a fail open pneumatic actuated valve by mistake. I needed a fail closed one. What can I do? A: To make the change just remove the actuator from the valve and turn it, or the valve stem, 90 degrees and remount the actuator.
Q: 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? A: 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.
Q: How do I wire up my electric actuator? A: 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.
