Characteristics
All welded structure, light weight of valve
Pure metal hard seal, stainless steel seat, valve plate, excellently overcome the problem of impurities in the pipe network
Three eccentric, anti-seize floating valve seat design, metal U-ring seal ring with elasticity, can adapt to temperature and pressure changes within working conditions
There are national standard and European standard for welding end, which can be directly welded to the pipeline without preheating.
Long valve neck design for easy insulation
The valve series are all designed for double half shaft, high Kv circulation value
The nominal pressure and sealing pressure can reach PN25.
Designed and produced according to EN488 standard (300N/mm 2) sealing standard according to EN12266-1, class B. Two-way seal of the same grade (up to a higher level according to special requirements)
All valves are tested in strict accordance with the pressure equipment test standard 97/23EC
