Working principle and advantages of pneumatic valve

The working principle of pneumatic valve is rotating pneumatic pneumatic valve stem to open and close. Pneumatic valve switch lightweight, small size, large diameter can make it, good sealing, simple structure, convenient maintenance, and facial sealing surface often in the closed state, not easily be medium erosion, has been widely used in various industries. Pneumatic valve advantages:

1. Fluid resistance is small, its resistance coefficient with section of equal length.
2。 Simple structure, small volume, light weight.
3。 Close and reliable, pneumatic valve sealing surface of materials widely used plastic, sealing good, also has been widely used in the vacuum system.
4。 Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.
5。 The pneumatic valve has simple structure, convenient maintenance, sealing ring, which generally remove replacement is more convenient.
6。 In full open or full close, the body and the pneumatic valve seat sealing surface and the dielectric isolation, medium through, can not cause erosion of pneumatic valve sealing surface.
7。 Applicability is wide and size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
