Trunnion Mounted 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, etc. are designed for a special consideration for a variety of corrosive and non-corrosive media .
Compared with the floating ball valves, work, force the valve before the fluid pressure on the ball is passed to produce all the bearings, so that the ball does not move to the seat, so the seat does not put too much pressure, so Trunnion Mounted ball valve torque is small, seat deformation, stable sealing performance, long life, suitable for high pressure, large diameter occasions. Advanced spring pre-seat assembly, with self-tightening properties upstream seal achieve. Each valve has two seats in each direction can be sealed, so the installation does not flow restriction is bidirectional. This valve is usually installed horizontally.
There are two type Trunnion Mounted ball and three type two body structure, bolted flange sealing with PTFE inserts into the stainless steel circle, a spring steel ring to ensure the rear seat close to the ball, remain sealed. Upper and lower stems are equipped with PTFE bearings, reducing friction and effortless operation, with a small shaft bottom tabs to ensure access at the position of the ball and seal. Full Bore: valve flow aperture consistent with the internal diameter of the pipeline to pipeline cleaning.
