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.
