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