Product Details

Pneumatic diaphragm control valve is the terminal industrial process measurement and control system control device, is composed by pneumatic diaphragm actuator, direct through single-seat,double seat and sleeve valve, etc., which can automatically change the valve trim position according to the control signal system , changing the flow area between the valve trim and the valve seat, to change the valve drag coefficient, to realize the regulation for the medium flow, pressure and level and other process parameters adjustment. 

ZXN series Pneumatic double seat Control Valve Characteristics:

Using the new ZXN multi-spring actuator instead of the old ZMA/B actuator, with the advantages of low height, light weight, easy installation and maintenance. The fluid thrust works on the upper and lower valve core have opposite direction and similar size. Imbalance force is very small, allowing a large pressure.
