fixed ball valve

Product overview:

The fixed ball valve is a new generation of high-performance ball valve. Special considerations have been taken in its design such as strength, safety, and resistance to harsh environments. It is suitable for various corrosive and non-corrosive media. Compared with the floating ball valve, when it works, the force generated by the fluid pressure in front of the valve on the ball is all transmitted to the bearing, and the ball will not move to the valve seat, so the valve seat will not bear excessive pressure, so the fixed ball valve It has small torque, small valve seat deformation, stable sealing performance and long service life. It is suitable for high pressure and large diameter occasions; it is widely used in petrochemical, coal chemical, nuclear power, aerospace, natural gas, electric power, metallurgy, food and other industries.

Product Details

Features:

Reliable sealing:

The valve adopts a spring-loaded valve seat combination structure, which ensures sealing, flexible opening and closing without jamming even when pressure and temperature fluctuate in a wide range.

Large flow design:

The valve body adopts a full-bore design, with strong flow capacity and small flow resistance, making it easy to clean the pipeline.

Locking device:

The locking device design ensures that the valve is in the correct switching position to prevent misoperation.

Fireproof structure:

When a fire occurs, once the valve seat is burned, the ball will directly contact the metal surface on the valve body, thereby preventing a large amount of medium from leaking from the burned valve seat.
