What are the advantages of the pneumatic valve?

Pneumatic valve applies to truncate or on line in the medium. Different materials can be respectively suitable for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, and other media. Pneumatic valve in the pipeline is mainly used for cutting speed is quick, distribution, and change the flow direction of medium. Fluid resistance is small, its resistance coefficient with section of equal length. Simple structure, small volume, light weight. Close and reliable, and the valve sealing surface material widely used plastic, sealing good, also has been widely used in the vacuum system. Easy to operate, open and close quickly, from open to close as long as the rotating °, is advantageous for the remote control. The pneumatic valve has simple structure, convenient maintenance, sealing ring, which generally remove replacement is more convenient. In full open or full close, the body and seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion. Applicability is wide and size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied. Pneumatic valve has been widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, as well as People's Daily life.
