ZJHP pneumatic film single seat regulating valve adopts top guiding structure. The valve body is compact, the flow passage is S-streamlined, the pressure drop is small, the flow rate is large, the adjustable range is wide, and the flow characteristic precision is high. The guide part of the spool has large guiding area and strong anti-vibration performance. The seat closing performance meets the GB/T4213-92 standard. The control valve is equipped with multi-spring film actuator, which has small structure output force and is more suitable for high temperature applications requiring high reliability and closing performance, low temperature and small pressure difference between front and back of the valve.
