pneumatic actuator cut off lining butterfly valve
It is consist of pneumatic actuators and lining butterfly valve, they supporting using with solenoid valve, pressure reducing valves (the air dealing parts), accept the 24VDC or 220VAC voltage control signal, medium in the pipeline could be properly control
pneumatic actuator regulating lining butterfly valve
It is consist of pneumatic actuators and lining butterfly valve, they supporting using with solenoid valve, pressure reducing valves (the air dealing parts), accept the 0-20madc voltage control signal, medium in the pipeline could be properly control
The products is using in the working conditions of medium like Sulfuric acid, hydrofluoric acid, nitric acid, phosphate, chlorine, Strong base, Aqua regia and so on
Application of the industry:
chemical industry
oil refining industry
pesticide industry
Water conservancy industry
Municipal industry
