ZJHP type pneumatic single seat adjusting valve composed of multi-springs film actuator and low flux single valve. New actuator have low height, low weight, easy installance and checking. The new impact body structure have free path and large flow modulus.

This product operates steadly, action characteristic is reliablely, with exiguity seat leakage, precise flow characteristic, and wide adjusting range, etc. We believe that by right of special strongpoint, this procduct will achieve high quality controling effect in wide area.
