Purchase Guide

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
