1.Wear resistance; As a result of the hard seal ball valve valve core is alloy spray welding, sealing ring is alloy steel welding, so hard seal ball valve when the switch is no wear and tear. (its hardness coefficient for 65-70) :
2. Good sealing performance; Because of the hard sealing ball valve's sealing is using artificial grinding, until the valve core and seal perfectly before using. So he sealed performance is reliable.
3.Light switch; Due to adopting the spring hard seal ball valve at the bottom of the sealing ring seal and valve core embrace together tightly, so in the outside powers over spring pre-tightening force when the switch is very light.
4.Long service life, has been widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, as well as People's Daily life.
1. The fluid resistance is small, little flow resistance full size of ball valve.
2. Simple structure, small volume, light weight.
3. Compact and reliable. It has two seal face, and widely used all kinds of plastic ball valve sealing surface of materials, good sealing, can realize completely sealed. Have been widely used in the vacuum system.
4. Easy to operate, open and close quickly,High-performance ball valve from fully open to close just rotate 90 °, is advantageous for the remote control.
5. Easy maintenance, simple structure of ball valve, sealing ring, which generally remove replacement is more convenient.
6. In the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, medium through, can not cause the valve sealing surface erosion.
7. Applicable scope is wide, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
8.wipe because of ball valves in the process of opening and closing and so can be used to bring in the medium of suspended solid particles.
High machining precision, expensive and should not be used in high temperature, such as pipe contains impurities, easily blocked by impurities, lead to valve cannot open.
