Conbraco 10-614-15 Relief Valve

The Conbraco 10-614-15 is a high-capacity hot water pressure relief valve engineered for heavy-duty protection in commercial and industrial boiler systems. Featuring a 3/4" FNPT inlet and a 1" FNPT outlet, this bronze-bodied safety valve is factory-set at 75 PSI to prevent over-pressurization in large-scale hydronic heating installations. With a discharge capacity of 1,977,000 BTU/hr, it satisfies the rigorous demand of high-output systems. The Apollo 10-600 series design utilizes a high-volume flow path and a silicone seat to ensure positive shut-off and resistance to scale build-up. This ASME Section IV certified valve is a standard replacement for HVAC contractors maintaining large boilers where reliable thermal expansion protection is non-negotiable. Its corrosion-resistant internal components and heavy-duty spring provide stable performance across high-temperature cycles, ensuring the pressure relief setting remains accurate under demanding field conditions.

Key Benefits for Technicians:

• High BTU Rating: Rated at 1,977,000 BTU/hr to support large commercial boilers and water heating systems.
• Durability: Constructed with a bronze body and stainless steel springs for long-term reliability in harsh environments.
• Code Compliance: Meets ASME Section IV requirements for heating boilers, facilitating easy inspections and safety adherence.
• Optimized Flow: The oversized 1-inch outlet minimizes backpressure during discharge, ensuring maximum relief valve capacity.

Common Questions:

What is the maximum operating temperature for the Conbraco 10-614-15?
This valve is designed for hot water heating boilers and is rated for temperatures up to 250°F.

Can this valve be installed horizontally?
No, for proper operation and to meet safety codes, this relief valve must be installed in a vertical position with the drain piping sloped for gravity flow.

Is the 75 PSI setting adjustable in the field?
No, this unit is factory-set and sealed at 75 PSI. Tampering with the seal voids the ASME certification and poses a significant safety risk.
