Bell & Gossett ASME Safety Relief Valves

Features and Benefits:

  • Engineered in accordance with Section IV of the ASME boiler and pressure code for heating boilers with capacities certified by the National Board of Boiler and Pressure Vessel Inspectors.
  • Offer the highest BTUH ratings available on the market today for valves in their class (790,000 to 5,999,000 BTUH)
  • EPDM diaphragm operated (cast iron models) and diaphragm assisted (bronze models) have an effective area approximately 5 times greater than conventional “pop-type” ‚ÄĚrelief valves to help overcome the effects of fouling.
  • Low differential between opening and closing pressures helps to prevent conditions under which system water might flash to steam and cause hammering
