Conbraco 10-605-34 Relief Valve

The Conbraco 10-605-34 is a high-capacity hot water boiler pressure relief valve engineered for large-scale commercial and industrial hydronic heating systems. Featuring a 1" FNPT inlet and outlet, this ASME Section IV certified valve is factory set at 150 PSI to provide critical overpressure protection. With a substantial discharge capacity of 5,044,000 BTU/hr, it is designed to handle the rigorous demands of high-output boiler systems where reliable thermal expansion relief is non-negotiable. The construction utilizes a premium bronze body and a silicone seat to ensure positive shut-off and resistance to scale buildup, maintaining system integrity under high-temperature conditions.

For contractors managing HVAC system safety, the 10-605 series offers a high-flow design that minimizes pressure drop during emergency discharge. This high capacity relief valve is a standard choice for commercial boiler maintenance, offering a corrosion-resistant stainless steel spring and a non-stick diaphragm. Precise alignment of the stem and sea ensures consistent popping pressure and reseating, making it a dependable component for hydronic heating pressure relief applications.
