The ball of the ball valve is floating. Under the medium pressure, the ball can produce a certain displacement and press tightly on the sealing surface of the outlet end to ensure the sealing of the outlet end.
It is characterized by compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are usually closed, not easy to be eroded by media, easy to operate and maintain. It is suitable for general working media such as water, solvent, acid and natural gas.

Blowout proof stem of ball valve：
The ball valve stem is made of a shoulder at the bottom end. It is held by the valve body to prevent the valve stem from accidentally coming out of the valve under certain working conditions. Other designs for the Stainless Steel Ball Valve are available upon request.
Because the ball and stem in the Stainless Steel Ball Valve are suspended from non-metallic parts, ie seat seals and stem seals, the stem and ball may generate static electricity. Mechanical devices (anti-static metal springs and balls) are designed Used to hold the metal between the rotating ball/stem and the valve body.
