Details
Fixed ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipelines, its strength, safety, and resistance to harsh environments have been specially considered in design, and it is suitable for various corrosive and non-corrosive media . Compared with the floating ball valve, when it is working, the force generated by the fluid pressure in front of the valve on the ball is all transmitted to the bearing, which will not make the ball move to the valve seat, so the valve seat will not bear excessive pressure, so the fixed ball valve Small torque, small deformation of valve seat, stable sealing performance, long service life, suitable for high pressure and large diameter occasions. Advanced spring pre-seat assembly with self-tightening characteristics to achieve upstream sealing.
Fixed ball valves are suitable for various pipelines of Class150～Class1500, PN16～PN100, JIS 10K～JIS 20K, and are used to cut off or connect the medium in the pipeline. Different materials are used to transport water, steam and oil respectively. Products, nitric acid, acetic acid, oxidizing medium, urea, etc., widely used in petroleum refining, long-distance pipeline, chemical industry, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other fields. The drive mode of fixed ball valve is worm gear transmission, manual, pneumatic or electric. Fixed ball valves generally adopt flange connection, but also can use butt welding connection.
