How to choose pneumatic ball valves and butterfly pneumatic valve force word pneumatic valve manufacturer analysis are given

pneumatic ball valves and butterfly pneumatic valve is compared commonly used pneumatic valves. Some occasions can be common, but some operating mode is used only in one. Primary differences lies in the structure and principle of switch. Force word pneumatic valve manufacturer gives brief analysis:
a, pneumatic ball valve, cock and in the light of the pneumatic valve, opening and closing is sphere. Fluid resistance small, full size of the pneumatic ball valve is no flow resistance. Construct a brief, small volume, light weight. Closely. It has two sealing surface, and now the pneumatic valve sealing surface material widely used in all kinds of plastic, good sealing, can accomplish completely sealed. Have been widely used in the vacuum system. Open and close operation is convenient, agile, from open to close as long as the rotating °, to facilitate remote manipulation. Convenient repair, pneumatic ball valve structure brief, sealing ring are often activity, open convenient replacement are compared. In full open or full close, the sphere and the pneumatic valve seat sealing surface and the dielectric isolation, medium through, does not cause corrosion of pneumatic valve sealing surface. Wide scale of application, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be used. Because pneumatic ball valve in the process of opening and closing swab with sex, so can be used to bring in the medium of suspended solid particles.
2, pneumatic butterfly valve, opening and closing a disc type is at the mercy of an open,
the characteristic is:
, construct a brief, small volume, convenient device;
and flow resistance coefficient is small, agile,;
, can be used in large diameter pneumatic valves;
, can use different sealing surface, use all kinds of environments, including powder and granule medium;
quick, convenient for opening and closing, energy saving, fluid resistance small, can often operate.
and can transport the mud, and the apertures accumulated liquid at least.
and low pressure, can accomplish outstanding seal.
and regulate performance is good.

3 and summarizing control pneumatic valve relative to the pneumatic ball valve, sealing is a bit poor, but large diameter pneumatic valve, pneumatic valve adjustment than pneumatic ball valve has a unique advantage; As unavailable, regulate flow pneumatic valve regulate small butterfly, and V control pneumatic ball valve, regulate accurately. Else, in high-pressure pipe, pneumatic ball valve pneumatic valve has advantages than a butterfly.
