ZJHP small pneumatic membrane single seat regulating CSGO¾º²Â
Summary ZJHP small pneumatic thin film single seat regulating CSGO¾º²Â is composed of pneumatic thin film multi spring actuator and fine single seat CSGO¾º²Â. The multi spring actuator is of low height, light weight, simple equipment, compact structure, smooth flow path, and large flow coefficient. It is suitable for occasions with strict leakage requirements, low pressure difference before and after the CSGO¾º²Â, and a certain viscosity and a small amount of fiber medium.
