| S2 model is a self-operated fully balanced excess pressure relief valve. It’s used to maintain the pressure upstream of the valve to an adjusted set point.
This excess pressure valve can not replace a safety valve. When upstream pressure rises above a set point, the valve opens proportionally pressure rising. Application : This model of regulator is suitable for steam, compressed air, no hazardous gases and liquids. Regulation range : 20 mbar to 8 barg. with different actuators. Diameters : DN15 to DN100 Flanges : Materials : Trim Stainless steel AISI 304, body in ductile iron, carbon steel or stainless steel 1.4408. ATEX Several models of excess pressire valves / dischargers exist (threaded, ISO, ANSI, liquid, gas, steam …), do not hesitate to contact us to discuss your needs. |
