Watts F274428 174A Series 3/4" Water Pressure Relief Valve, 30 PSI

Watts F274428 Details

This Watts 3/4" water pressure relief valve is designed to be used for pressure protection for your boiler equipment. It features female 3/4" NPTF inlets and outlets and a bronze valve body. It's a direct replacement for the one that came with select boilers, and it's used to replace a worn or broken part in order to relieve below the maximum boiler working pressure.

This relief valve has a seat located above the drain to ensure water is never trapped and sediment never fouls the seat. It features a nonmechanical seat-to-disc alignment that won't stick or freeze. Plus, it comes with a nonrestrictive discharge drain line flood sensor with SentryPlus Alert (required activation kit to activate sensor is sold separately), which detects excessive water discharges from the relief valve. It has a pressure relief setting of 30 PSI and a pressure range of 30-150 PSI with BTU ratings from 650,000 to 14,360,000 BTU per hour, and it has a maximum temperature of 250 degrees Fahrenheit. This item is for non-potable applications only.
