ASME Safety Relief Valves
Protect fired and unfired hot water vessels against hazardous operating pressures.
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" relief 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
Model 3301 and 4100 Operating Data & Construction
Maximum working pressure 50 PSIG (3.4 bar)
Maximum Operating Temperature 250 F (121 C)
Body: Cast Iron
Diaphragm & Seat: EPDM
Internal Wetted Parts: Brass

Product Q&A
1 Question1 Question
Q: Can you replace just the top portion of the safety valve and bypass taking the valve body off of the line, in other words can you leave the old body and replace just the top portion of the valve?

Verified Reply- SupplyHouse StaffNo, unfortunately replacement parts are not available. The entire relief valve would need to be replaced.
