Conbraco 10-407-05 Safety Relief Valve 30 Psi 3/4 Inch

Product Description

The CONBRACO 10-407-05 is a uni-body brass and bronze safety relief valve rated at 30 PSIG set pressure for use in hot water heating and hydronic heating applications. Built to ASME Section IV standards, it features a stainless steel spring for reliable, corrosion-resistant operation across a temperature range up to 250 degrees F. The 3/4-inch male-threaded inlet and 3/4-inch female-threaded outlet allow straightforward inline installation. Licensed plumbers and HVAC hydronic technicians install this valve as an overpressure protection device on residential and light commercial hot water boilers and hydronic heating systems. It weighs 0.62 pounds.

This valve is designed for hot water heating boilers and hydronic heating systems operating at set pressures of 30 PSIG. It is registered in all Canadian provinces and territories under CRN 0G8547.5C, making it suitable for installations across the United States and Canada. The high-capacity design suits residential boiler applications where ASME Section IV compliance is required. The uni-body construction reduces potential leak points compared to multi-piece assemblies.

Compatibility

Designed for use with hot water boilers and hydronic heating systems requiring ASME Section IV safety relief valve compliance at a 30 PSIG set pressure rating.

Installation Notes

Installation should be performed by a licensed plumber or qualified hydronic heating technician in accordance with applicable local codes and ASME guidelines. Shut down the boiler and allow system pressure and temperature to fully dissipate before removing or installing any pressure relief valve. Install with the valve body oriented so the discharge outlet directs safely away from personnel and toward an approved drain or discharge pipe. Never cap, plug, or restrict the discharge outlet of a relief valve.
