steel trunnion ball for ball valve

trunnion sphere are mainly used for floating ball valves. Its main feature is that the ball has no supporting shaft, the ball is held by the two seats in a "floating" state, solid sphere in the pipeline is mainly used to cut off, distribution and change the direction of the flow of the medium. With the corresponding seat sealing design, reliable reverse seal valve stem, fire static function, automatic pressure relief and locking device and other structural features. Can be used in chemical industry, petroleum, natural gas, metallurgy, and other industries and containing hydrogen sulfide medium, impurities, serious corrosion of natural gas pipeline. Ball valve material based on: ordinary carbon steel series (WCB&A105); Stainless steel series (304,316); Low temperature steel series (LCB,LCC); Antisulfur series, etc., the material of the sphere can be changed correspondingly. Can be customized F304 F316, F51,F53 and other materials.
