Trunnion mounted Ball Valve DN350 PN16 WCB

Trunnion mounted Ball Valv is a new generation of high -performance ball valves. It is suitable for long -term pipelines and general industrial pipelines. Its strength, safety, and harsh environmentality are specially considered during design. It is suitable for various corrosive and non -corrosive media Essence Compared with the floating Ball Valve, when working, the force of the fluid pressure of the front of the valve on the sphere is passed to the bearing, which will not move the sphere to the valve seat. Therefore, the valve seat will not bear too much pressure. The torque is small, the valve seat is deformed, the sealing performance is stable, and the service life is long. It is suitable for high -pressure and large caliber occasions. Advanced spring pre -valve seat components have self -tight characteristics and realize upstream sealing. There are two valve seats in each valve, and each direction can be sealed, so the installation does not have a flow limit, which is two -way. This valve is generally installed horizontally

The advantage of Flange Trunnion Mounted Ball Valve

1. Save forceful operation: The sphere is supported by the upper and lower bearing to reduce friction, eliminating excessive torque caused by the huge sealing load formed by the import pressure to promote the formation of the sphere and sealing seats.
2. The sealing performance is reliable: PTFE monomer material sealing ring is embedded in stainless steel valve seats. The tail end of the metal valve seat has a spring to ensure that the sealing ring is sufficient. The valve continues to ensure good sealing performance.
3. Fire prevention structure: In order to prevent the occurrence of a tetrafluoroethylene sealing ring due to the occurrence of sudden heat or fire, a large leakage occurs, and the fire is provided, and the fire -resistant sealing ring is set up between the sphere and the valve seat. Under the action of spring force, the sealing ring of the valve seat is quickly pushed to the sphere to form a metal and metal seal to a certain degree of sealing effect. The fire resistance test meets the requirements of APL6FA and APL607 standards.
4. Automatic pressure discreation function: When the stagnant medium stagnation in the valve increases abnormally more than the pre -for force of the spring, the valve holder is retreated and separated from the sphere to achieve the effect of automatic pressure discreation.
5. Expedition of the tube: The excretion holes are set up and down on the upper and lower valve body. You can check whether the valve seat is leaked. When the valve is in full or full level, the stress of the middle cavity can be removed and the filling can be replaced directly; the middle cavity can be discharged; Lest retention to reduce the pollution of the medium on valve.
