We are using carbon steel and stainless steel to manufacture our range of high pressure ball valves. Their body and stem seals are constructed using any of the three material viz Polytetrafluoroethylene (PTFE), Nitrile rubber (NBR) and fluoroelastomer (FPM). In the same context, ball seat is made using material such as PTFE, Polyoxymethylene (POM), Polyetheretherketone (PEEK) and others. Depending on the model selected, the ball valves can have a size of Â½ inches, Â¼ inches or others. Similarly, the pressure range can be up to 400 bar or 1000 bar. The temperature range of these valves is -40Â°C to +200Â°C.
