Fixed ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipeline, its strength, safety, resistance to harsh environments such as in the design of a special consideration, applicable to all kinds of corrosive and non corrosive media. The general level of fixed ball valve installation.

Compared with the fixed ball valve, floating ball valve work force, fluid pressure before the valve resulting in the ball on all transferred to the bearing, not to move the ball to the seat, the seat would not put too much pressure, so the torque of the fixed ball valve, valve seat sealing small small deformation, stable performance, long service life, suitable for high pressure, large caliber occasions. Advanced spring pre seat assembly, self tight characteristic, and the upstream seal. Each valve has two valve seats, each direction can be sealed, so the installation does not flow restrictions, is bidirectional.

Fixed ball valve with flange, butt welding can also be adopted. Fixed ball valve for Class150 ~ Class1500, PN16 ~ PN100, JIS ~ 10K JIS 20K on various pipelines, suitable temperature: -196 to 350 DEG C, used to cut off or connect the line of medium, use different materials, can be separately applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, widely used in petroleum refining, pipeline, chemical, paper, pharmaceutical, water, electricity, municipal, steel etc..
