Product structure and use of forged steel ball valve three-split connection, the Department of the body in two parts along with the valve seat axis perpendicular to the channel cross-section is divided into three parts, the entire valve stem along the central axis symmetrical, it mainly used to cut off the pipeline, distribution, and change the direction of media flow. Structure to ensure its large pivot the ball accurately under high pressure center to ensure the good operating performance of the valve; standard seat structure by the spring, will push the ball valve seat to ensure a good two-way sealing performance of import and export; use own discharge valve, the valve body cavity may be out emissions; pivot blow protected by anti-structure, effectively prevent leakage; low friction coefficient of the bearing, so to minimize the torque, easy to open and close the valve; the stem and Effective body contact, so that superior performance anti-static grounding devices and so on. With excellent performance, high reliability and wide range of uses, reasonable prices and so on. 

 Forged steel fixed ball valve for: chemical, petroleum, natural gas, metallurgy, and other industries and hydrogen sulfide media, impurities, corrosion of the serious long distance gas pipelines.
