Q347F worm wheel trunnion mounted ball valve

The Q347F worm wheel fixed ball valve is connected into a forging steel fixed ball valve with three parts, which is divided into three parts along the two valve seat perpendicular to the axis of the valve channel. The whole valve is symmetrical along the center axis of the valve stem. It is mainly used to cut, distribute and change the direction of medium flow on the pipe. Its large pivot structure ensures accurate center position of the ball under high pressure to ensure good operating performance of the valve; the standard valve seat adopts the spring structure to push the valve seat to the ball and ensures a good two-way sealing performance of the inlet and outlet. The valve in the valve body can be discharged outwards; the pivot is protected by blowing out protection. Structure, effective prevention of leakage; low friction coefficient of the bearing, making the torque reduced to the minimum, easy to open and close the valve; the valve stem and the valve effective contact, so that the anti-static grounding device performance is superior. It has many advantages such as excellent performance, high reliability, wide use and reasonable price. It is suitable for chemical, petroleum, natural gas, metallurgy and other industries, and natural gas long-distance pipelines containing hydrogen sulfide, many impurities and serious corrosion.
