China Gear Operation Underground Fully Welded Ball Valve

Fully welded ball valve is widely used in various fields. Its superior quality and high performance stability is out of reach for ordinary cast steel ball valve, its service life is far greater than cast steel ball valve, full welded ball valve is widely used in city gas, urban heating, petrochemical industry, shipbuilding, steel, gas station, power plants and other kinds of pipe devices. All welded ball valve can be used long-term reliable operation, simple maintenance, valve installation of other is more convenient.
Fully welded ball valve application:
City gas: Gas output pipeline, main pipeline and manifold supply, etc.
Central heating: Large heating equipment output pipeline, main pipeline and feeder.
Heat exchangers, piping and the opening and closing of each circuit.
Steel mills: All kinds of fluid pipes, exhaust pipes, gas and heat supply pipeline, the fuel supply line.
All kinds of industrial equipment: All kinds of pipes, all kinds of industrial gas and heat pipe heat treatment.
Features:
One-piece full welded ball valve, there won't be the phenomenon such as external leakage, because the seat is made of carbide, fluorine, sealing ring and spring, the adapt capability to the change of pressure and temperature is strong, Under pressure and temperature change range will not produce any leakage. Smooth. Sphere of track, with advanced computer processing detector in the sphere of high machining accuracy. Because the body material is the same as the pipe material, no deformation will not occur because of the earthquake and the vehicle through the ground. When pipe ageing resistance. Sealing ring ontology is 20% C (carbon) content of PTFE material to guarantee no leakage (0%).
