Flange fully welded ball valves are widely used in various fields, its service life is much greater than cast steel ball valves, widely used in city gas, city heating, petrochemical, shipbuilding, iron and steel, regulating stations, power plants and other types of pipeline equipment, can be used in a long-term reliable operation, no maintenance, easy to install, so that the valve is more convenient to install other.
Uses:
1) City gas: gas output pipeline, the main line and various branch supply pipelines, etc..
2) Centralised heat supply: large-scale heat supply equipment output pipelines, trunk lines, branch lines.
3) Heat exchangers: pipelines and various circuits opening and closing.
4) Iron and steel mills: various fluid pipelines, exhaust gas discharge pipelines, gas and heat supply pipelines, fuel supply pipelines.
5) Various industrial facilities: various heat treatment pipelines, various industrial gas and heat pipelines.

Characteristics:
Flanged fully welded ball valve is one-piece type, there will be no external leakage and other phenomena, because the valve seat is composed of carbonised sealing ring and curry spring, so it has strong adaptability to changes in pressure and temperature, and will not produce any leakage slip within the range of marked pressure and temperature. The machining process of the sphere is tracked and inspected by advanced computer detectors, so the sphere is processed with high precision. As the material of the valve body is the same as the material of the pipeline, there will be no uneven stress and no deformation due to earthquakes and vehicles passing through the ground, and the pipeline is resistant to aging. The sealing ring body is made of PTFE with 20%C content, which guarantees no leakage (0%).
