Trunnion Ball Valve(Fixed ball valve) (1)Overview
fixed ball valve
Fixed ball valve is a new generation of high-performance ball valve,apply to long-distance pipeline and general industrial pipelines. Its strength, safety, resistance to harsh environment, etc. in the design of a special consideration, for a variety of corrosive and non-corrosive media. Compared with the floating ball valve, the work of fixed valve before the fluid pressure on the sphere of the force generated by all the bearings, will not move the ball to the valve seat, so the valve seat will not bear too much pressure, therefore, the fixed ball valve has Low torque, small deformation of the valve seat, sealing performance is stable, long life, suitable for high pressure, large caliber occasions. Advanced spring pre-seat components, with self-tightening characteristics, to achieve upstream seal. Each valve has two seats, each direction can be sealed, so the installation does not flow to the limit, is two-way. This valve is normally installed horizontally.
 
Fixed ball valve has two and three block two kinds of body structure, the flange with bolts, sealed with enhanced PTFE embedded in the stainless steel ring, the rear of the ring with a spring to ensure that the seat close to the ball, Keep the seal. Up and down the stem are equipped with PTFE bearings, reduce friction, operation effort, small shaft at the bottom with a adjustment piece to ensure that the ball and the seal of the junction position. Full diameter: Valve flow Aperture is the same as the inside diameter of the pipe for piping.
