Trunnion Mounted Soft Sealing Ball Valve
Brief instruction:
Trunnion mounted ball valve is mainly used in the pipeline to cut off, distribute and change the medium flow. The pivot structure of the fixed ball valve ensures accurate ball position. The standard valve seat uses a spring structure to push the valve seat towards the sphere, ensuring good low-pressure sealing performance. The valve seats on both sides of the ball valve can be sealed individually, that is, with two-way sealing characteristics. The fixed ball valve uses its own discharge valve to discharge the pressure in the cavity of the valve body. The pivot of the fixed ball valve adopts an anti-blowing protection structure and a low friction coefficient bearing, which has the advantages of excellent performance, high reliability, wide use and reasonable price. The valve is suitable for chemical, petroleum, natural gas, metallurgy, and other industries and long-distance natural gas pipelines containing hydrogen sulfide media, many impurities, and severe corrosion.
