ZJHP type Pneumatic Diaphragm Single Seat Control Valve adopts top guide structure, This type of valve has a compact structure, small pressure drop loss, large flow rate, wide adjustable range, and high accuracy of flow characteristics, and complies with the IEC60534-2-1-2011 standard. The leakage of the regulating valve complies with ANSI FCI 70-2-2013 standard. The structure adopts a pressure cage type to facilitate quick replacement of the valve spool and valve seat. At the same time, the valve seat sealing line is double-sided, extending the service life of the valve.
Single seated control valve is equipped with a multi-spring diaphragm or cylinder actuator, which has a compact structure and large output force.
