Pneumatic cut-off ball valve

Pneumatic cut-off valve is a type of actuator in automation systems, consisting of a multi spring pneumatic diaphragm actuator or piston actuator and a regulating valve or globe valve body. It receives signals from regulating instruments and controls the cutting, connection, or switching of fluids in process pipelines. It has the characteristics of simple structure, sensitive response, and reliable action. It can be widely applied in industrial production sectors such as petroleum, chemical, and metallurgical industries. The air source of the pneumatic cut-off valve requires filtered compressed air, and the medium flowing through the valve body should be liquid and gas without impurities and particles.
The pneumatic cut-off valve adopts a soft sealing structure, designed with working seal and maintenance seal, with small operating torque, moderate sealing pressure ratio, reliable sealing, sensitive action, easy to achieve automatic control through hydraulic control, and long service life. Widely used in industries such as petroleum, chemical, metallurgy, papermaking, pharmaceuticals, electroplating, etc.
