4100-30 4100K Relief Valve

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
