    Introduction to American standard fixed ball valve

    American standard fixed ball valve, is a new generation of high-performance ball valve, suitable for long-distance pipeline and general industrial pipeline, its strength, safety, resistance to harsh environment and other special considerations in the design.

    Suitable for all kinds of corrosive and non-corrosive media. Compared with the floating ball valve, when working, the force generated by the fluid pressure in front of the valve on the ball is all transferred to the bearing.

    The ball will not move to the seat, so the seat will not bear too much pressure, so the fixed ball valve torque is small, small deformation of the seat, stable sealing performance, long service life,

    Suitable for high pressure and large caliber occasions. Advanced spring pre - seat assembly with self - tightening characteristics for upstream sealing. Each valve has two seats that seal in each direction,

    Thus the installation has no flow limitation and is bidirectional. This valve is normally installed horizontally.
