4 Keys to Troubleshooting a Valvcon Electric Valve Actuator

The Valvcon Electric Valve Actuator provides accurate, zero-emission control of control valves and can tie in to a PLC or RTU for remote monitoring. 

In this video, Alex shows you four things to look for when troubleshooting your actuator.  

Problem 1: Your Motor Stall LED light is blinking in a mid-travel position.

Solution: This may be due to the Valvcon hunting for a signal. To correct this problem, increase the actuator dead band set point by rotating the dial clockwise.

Problem 2: Your actuator does not respond to 4-20mA or 0-10V control signal.

Solution: Fully rotate the “Analog Position Control Mode” dial clockwise to confirm that it has been selected.

Problem 3: You’re not getting Feedback in Energy Save mode.  

Solution: If this happens, even briefly, the Feedback signal is turned off. More than likely, someone removed the Feedback wires from the terminal block. Connect the wires and then cycle power to reinstate Feedback signal. 

Problem 4: Your LED lights shut off after a minute.  

Solution: Check to see if Energy Save mode has been selected.

LED lights are turned off after one minute in Energy Save mode in order to reduce power consumption.

If any of these problems persists after troubleshooting, you can re-calibrate the actuator to reset the unit. If you need assistance, follow our video How to Install and Calibrate the Valvcon Actuator.

Use these quick tips to make sure your control valves are sized correctly, and production is operating at maximum capacity.
