The general purpose and characteristics of pneumatic valve

the general pneumatic valve suitable for: aviation kerosene, light oil, natural gas, liquefied gas, pipeline gas, chemical pipe, such as medium as truncation medium ideal device.
points:
1) pneumatic valves in the process of switch, pneumatic valve sealing surface and sliding vane seal face without any contact, therefore, no friction, wear, long service life of pneumatic valve, switch moment;
2. Pneumatic valve in the maintenance, do not need pneumatic valve from the line will be removed, just put the bottom cover pneumatic valve apart, changing a pair of sliding vane, maintenance is very convenient.
(3) pneumatic valve body and cock for reducing, can reduce cost;
4. Pneumatic valve body cavity with hard chromium plating, seal hard and glossy area;
(5) on the elastic sliding vane seal using fluorine rubber, and molding in the slide groove surface. With fire prevention function of the metal to metal seal as the backing of elastic seal;
6 pneumatic valves with automatic discharge device ( Alternative, after pneumatic valve fully closed to prevent the abnormal pressure pneumatic valve cavity and to examine the effects of pneumatic valves;
7) pneumatic valve switch position indicator and synchronization, can accurately show the pneumatic valve switch state.
