High Performance Steam Safety Valve
This is a safety valve that meets the requirements of Section I of the ASME Boiler and Pressure Vessel Code. The overpressure is opened within 3% and closed within 4%. It usually has two adjusting rings. It is commonly used as overpressure protection for steam systems and boilers in high temperature above 350°C. The bonnet extension protects the spring away from high temperature steam.
