Part Number
ASME Safety Relief Valves protect fired and unfired hot water vessels against hazardous operating pressures.
Nos. 3301 & 4100
• 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)
• Low differential between opening and closing pressures helps to prevent conditions under which system water might flash to steam and cause hammering.
• EPDM diaphragm operated (cast iron models) and diaphragm assisted (bronze models) have an effective area approximately 5 times greater than conventional “pop-type” relief valves to help overcome the effects of fouling.
