◆ American standard fixed ball valve closing member ball rotates around the center line of the valve body to achieve opening and closing. The sealing member is embedded in the stainless steel valve seat, and the end of the metal valve seat is equipped with a spring. When the sealing surface is worn or burned, Under the action of the spring, the valve seat and the ball are pushed to form a metal seal. It has a unique automatic pressure relief function. When the medium pressure in the valve cavity exceeds the spring preload force, the valve seat at the outlet end retreats from the sphere to achieve the effect of automatic pressure relief. After pressure relief, the valve seat automatically resets. It is suitable for water, solvent, acid And natural gas and other general working media, but also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc., are widely used in various industries.

Design Feature+

◆ It adopts cylindrical spring or wave spring preloaded movable metal valve seat structure, reasonable sealing pre-tightening force design, flexible closing and opening, effectively ensuring the reliability of sealing.

◆ The valve stem with a special structure device not only ensures that the filling material will leak, but also prevents the valve stem from coming out.

◆ According to the needs of users, it can be designed to adapt to the structure of dust (including solid particles), slurry and other media, so that the ball valve has better wear resistance and high temperature resistance.

◆ It has fire-proof and anti-static function.

◆ The structure of the ball valve should be used in accordance with the specified flow direction.
