product advantages:

1. The fluid resistance is low, its resistance coefficient equal with the same length  of pipe .

2. It has Simple structure, small volume and light weight.

3. Because of good sealing , reliable structure, not only it widespread use of plastic ball valve sealing surface of materials, ,but also has been widely used in the vacuum system.

4.it is Easy to operate, open and close quickly and from open to close just rotate 90 degree, so that it has advantage for the remote control.

5. because of  pneumatic ball valve has simple structure, sealing ringand which generally remove replacement is more convenient.so that it is Easy maintenance.

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. Pneumatic hard seal ball valve has been widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, as well as People's Daily life.

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.
