What is the advantage of cast iron ball pneumatic valve

cast iron ball of pneumatic valve is applied to working temperature ℃ or less non corrosive medium such as water, steam piping, for opening and closing. The advantage of its opening and closing fast. In addition, its what advantage? Small make up for you here today introduces advantages of pneumatic valve, cast iron are as follows:
, fluid resistance small, basic no full size of the pneumatic ball valve flow resistance.
, simple structure, small volume, light weight.
, compact and reliable. It has two sealing surface, and the pneumatic ball valve sealing surface of materials widely used all kinds of plastic, good sealing, can realize completely sealed. Have been widely used in the vacuum system.
, convenient operation, opening and closing rapidly, from open to close as long as the rotating °, is advantageous for the remote control.
, convenient maintenance, pneumatic ball valve has simple structure, sealing ring, which generally remove replacement is more convenient.
when, in the full open or full close, sphere and the pneumatic valve seat sealing surface and the dielectric isolation, medium by, do not cause the erosion of pneumatic ball valve sealing surface.
, wide applicable scope, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
, because in the process of the pneumatic ball valve in the opening and closing is wiped, so can be used to bring in the medium of suspended solid particles.
