Benefits Of ON/OFF Type Electric Actuator:
ON/OFF type electric actuator provides you with a simple fluid control solution. This electric actuator is a quarter-turn rotary actuator for ball valve and butterfly valve. It could feedback the signal to the control system when the valve opens or close fully. Helping you know the valve station easier.
Available in AC or DC power supply.

- Confirm the valve size, valve material and working pressure. Those 3 points will affect the torque of the actuator. So please help to confirm those 3 points then we will advise the right model for you to allow your valve to open/close smoothly.
On the other hand, if you know the torque needed, it is a great help for us to select a model!
- Confirm the working temperature. If the working temperature is high, we will suggest the actuator with a bracket to protect the actuator far from the medium to ensure the lifespan of the actuator
- Confirm the size of the platform and coupling. We will help you confirm the connection size step by step. And make sure the actuator and valve are properly connected
