PN25 DN50-600 Underground Ball Valve with a Diffusion FunctionIntroductionDue to that the integrated structure, the vlave adopts the full welding process structure, the inner and outer seal of the valve is greatly improved and the valve weight is greatly reduced ( especially under DN300). The installation of...

Fully welded ball valves are opening and closing devices used for full opening and full closing.
This device is composed of a carbonized PTFE sealing ring and a disc spring, so it has strong adaptability to changes in pressure and temperature, and will not produce any leakage within the marked pressure and temperature range.
1.Floating Ball/Trunnion Mounted.
2.Full bore/Reduced port.
3.Metal seal/Soft seal.
4.Fire Safe Design; Anti-static device; Blow-out proof stem.
5.Belleville spring ensure no leakage.
