I. Overview of Pneumatic Trunnion Mounted Ball Valve
The Q647F pneumatic trunnion mounted ball valve is widely used in the exploitation, refining, processing, and pipeline transportation systems of petroleum, natural gas, coal, and ore; in the production of chemical products, pharmaceuticals, and food; in the power generation systems of hydropower, thermal power, and nuclear power; in the water supply and drainage, heating, and gas supply systems of cities and industrial enterprises; in agricultural irrigation and drainage systems; and in metallurgical production systems. It is an important mechanical product closely related to production and construction, national defense construction, and people's lives. Ball valves are enclosed in various pipeline systems to cut off or connect the medium flow, so that the medium is transported to each designated point according to a predetermined procedure.
