Watts F274428 LF174A Series 3/4" Water Pressure Relief Valve with Flood Sensor and Retrofit Connection Kit, 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 on your equipment.

Included with this valve is a nonrestrictive discharge drain line flood sensor with SentryPlus Alert and a retrofit connection kit for activation, which detects excessive water discharges from the relief valve. This sensor and kit are easy to install, customizable for wet threshold and timer delay, and provide connectivity to third-party building management systems. The retrofit connection kit flags temperature and pressure issues, as well as potential preventative maintenance. It connects to BMS through dry contact and does not required communication protocol integration.

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 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.
