Product Description


The DC series multi-spring diaphragm actuator converts the output pressure of the pneumatic regulating instrument into the change of the push rod displacement. Therefore, when it is connected with the body of the regulating valve, it can move the valve plug to the position corresponding to the input signal.

The actuator adopts multi-spring diaphragm, so it has the characteristics of compact structure and large output force.
