Features
Fluid resistance small, the drag coefficient with the same length of pipe. Simple structure, small volume, light weight. ||| closely reliable, valve sealing surface material widely used plastic, good sealing performance, in the vacuum system has also been widely used. ||| operation is convenient, quick open and close, from fully open to fully closed as long as the rotation 90 °, facilitate remote control. ||| repair convenient, simple pneumatic valve, seals are generally activities, the removal of the replacement is more convenient. In the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, the medium through, will not cause erosion of the valve sealing surface. ||| pneumatic valve has wide range of application, from small diameter to a few millimeters, a few meters from the high vacuum, high pressure can be applied. Widely used in petroleum, chemical, electric power, papermaking, atomic energy, aerospace, rockets and other departments, and in daily life. |||
