Wafer stainless steel ball valves, Italy type, size from 1/2'' to 8'', pressure PN16/PN40/150LB/JIS10K are available for different market.
Generally we manufacture stainless steel materials, such as 304, 316.etc., customer could customize materials which they need. Materials are depends on pipeline fluid medium, which have corrosion or not then to choose materials.
Wafer ball valve is soft seat, it could make zero leakage, which make valves have better performance. We mostly use PTFE, RPTFE, PPL, PEEK for seat and seal. Temperature range from -196C to 250C.
ISO5211 mounting pad is suitable for different actuators to make remote control.
