by:AIRWOLF     2021-01-25
As the name suggests, the pneumatic valve is a valve with pneumatic actuator. Pneumatic actuators execution speed is relatively fast, switching speed. Seconds/time, so usually also called pneumatic quick cut-off valve. Pneumatic valve usually configure various accessories, such as solenoid valve, air source treatment sanlian pieces, limit switch, locator, control box, etc. , in order to realize the local control and remote centralized control, in the control room can control the switch of the valve, do not need to run to the field or high altitude and dangerous manual control, to a great extent, save the human resources and time and safety. Pneumatic valve only need to use pneumatic operation USES air rotation operation and small rotational torque can be closed tightly. Full equality of the valve body cavity for medium resistance is very small, straight flow channel. Usually do think valve suitable for direct use. Valve itself is the main characteristics of compact structure, easy operation and maintenance, and is applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. The valve body can be a whole, also can
