1、 Overview of Pneumatic Piston Cut off Valve Products
The ZSQ pneumatic piston type cut-off valve of Shanghai Yuhu Company consists of a piston type pneumatic actuator and a cut-off valve. The pneumatic cut-off valve adopts a straight through single seat type, and the valve core within DN20 adopts a single guide structure, which can directly adopt a precision small valve body. The DN25-200 valve core adopts a dual guide structure, and the pneumatic quick cut-off valve has the characteristics of simple structure, easy operation, reliable use, and fast opening and closing. It directly controls the cut-off and circulation of the regulated medium according to signals from the control system or regulating instruments, achieving automatic control of parameters such as pressure, flow rate, temperature, or liquid level. Pneumatic quick shut-off valves are mainly used in automatic control systems for liquid and gas (oxygen) media that are free of impurities and particles, requiring quick and tight closure and rapid venting.
