3-Piece Flanged Stainless Steel Ball Valves
High-Temperature Flanged Stainless Steel Ball Valve
The high-temperature flanged stainless steel ball valve is a 3-piece flanged stainless steel ball valve equipped with high-temperature-resistant bearings and sealing elements where standard PTFE bearings are insufficient for hot process lines.
Operates between -40 °C and +250 °C. Available between DN15–DN100, with AISI 304 and AISI 316 options, in PN16 and PN40 pressure classes. Used in steam, thermal oil, hot air and high-temperature chemical lines.
