Product overview

The pneumatic film two-seat regulating valve adopts double-guide 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. Because of the guidance at the top and bottom of the spool, it has the characteristics of anti-seismic and anti-wear. The control valve is equipped with multi-spring membrane actuator, which has small structure and large output force. It is more suitable for good control under the process conditions requiring good stability, high reliability, high pressure, high pressure difference and easy blockage of silt impeller in fluid medium.
