Wholesale ANSI API Fixed Ball Valve Supplier

Wholesale ANSI API Fixed Ball Valve Supplier

Executive standard

Q347F American standard fixed ball valve is suitable for long distance transportation pipeline and general industrial pipeline, its strength, safety, resistance to harsh environment in the design of special consideration, suitable for a variety of corrosive and non-corrosive media. It is compared with the floating ball valve, when working, the fluid pressure before the valve on the ball on the force is all transferred to the bearing, will not make the ball to the valve seat, so the valve seat will not bear too much pressure, so the fixed ball valve torque is small, the valve seat deformation is small, the sealing performance is stable, the service life is long, suitable for high pressure, large diameter occasions. Advanced spring preseat assembly with self tightening feature for upstream sealing. Each valve has two seats, each direction can be sealed, so the installation has no flow restrictions, is bidirectional.
