How To Wire A COVNA Electric Actuator Valve?

Proper wiring helps the electric actuator valve to operate properly as well as smoothly, reducing maintenance costs. Different wiring methods can achieve different functions, such as on/off type and regulating type. Even different voltages will have different wiring requirements.

In this article, we will share 8 options of wiring diagrams of the COVNA electric ball valve and electric butterfly valve. Any problem with wiring of COVNA Valve, feel free to let us know. We are happy to help you solve the problem.

B Type: ON/OFF Type With Passive Contact Signal Feedback

Function: Finish open or close operations by the circuit, and the actuator outputs a set signal of passive position(Full opening, full closing)

Structure: With two neutral positions switches

C Type: ON/OFF Type With Resistance Potentiometer Signal Feedback

Function: Control the open angle of valves by circuit, and the actuator outputs the resistance signal corresponding to the position of switch

Structure: With 500Ω or 1,000Ω poentiometer

D Type: ON/OFF Type With Resistance Potentiometer and Neutral Position Signal Feedback

Function: Control the open angle of valves by cirsuit, and the actuator outputs the resistance signal corresponding to the position of open position, at the same time, oytpotting a set signal of passive position

Structure: Both potentiometer style and neutral positions switch style

E Type: Regulation Type With Servo Control Module

Function: Modulating input & output DC4-20mA, 1-5VDC, 0-10VDC

Structure: With servo control module and 1,000Ω potentiometer

F Type: DC24/ DC12V Direct ON-OFF Type

Function: The external cirsuit make positive and negative conversion of DC power to open or close, and the actuator outputs a set signal of passive position(Full opening, full closing)

G Type: AC380V Three-Phase Power Supply With Passive Signal Feedback

Function: The external cirsuit make positive and negative conversion of DC power to open or close, and the actuator outputs a set signal of passive position(Full opening, full closing)

Notes: Please kindly note if the switch position is correct when the three phase electric actuator is being adjusted, if it’s opposite direction, then make 2 of power lines exchange each other

H Type: AC380V Three-Phase Power Supply With Resistance Potentiometer Signal Feedback

Function: The external circuit make positive  and negative conversion of DC power to open or close, and the actuatoir outputs a set signal of passive position(Full opening, full closing)

Notes: Please kindly note if the switch position is correct when the 3 phase electric actuator is being adjusted, if it’s opposite direction, then make 2 of power lines exchange each other

Warm Tip: 

Please don’t connect one actuator parallel with other ones, in other words, can’t use the same controller contact points to control 2 or above actuators. Otherwise, it will cost out of control, motor overheating, product damage and shorter service life.
