WCB Forged Steel Worm Gear Flange Ball Valve

WCB Forged Steel Worm Gear Flange Ball Valve    Product Description  Sumary: American Standard Forged fixed ball valve-body connection, the Department of the valve seat in two parts along with the valve channel cross-section perpendicular to the axis is divided into three parts, the entire valve stem along the central axis of symmetry about it is mainly used in the pipeline to cut distribution and change the direction of media flow. Its large pivot structure ensures precise ball under pressure center position, the valve to ensure a good operational performance; standard seat with a spring structure, the seat into a sphere, to ensure a good seal performance bidirectional import and export; the use of self discharge valve with the valve body cavity can be discharged outwards; pivot using anti-blowout protection structure, effectively prevent leakage; bearing low friction coefficient, so the torque is reduced to a minimum, easy to open and close the valve; the valve stem and the effective contact, so that the superior anti-static grounding device performance. With excellent performance, high reliability, versatility, reasonable prices and other advantages. Applies to: chemical, petroleum, natural gas, metallurgy, and other industries and media containing hydrogen sulfide, impurities, corrosion serious long distance gas pipelines.   Main Technical Parameter:
