Conbraco 10-606-10 Relief Valve

The Conbraco 10-606-10 Relief Valve is a high-capacity safety solution engineered specifically for hot water heating boilers and large-scale hydronic systems. Featuring a 1-1/4" Female NPT inlet and a 1-1/4" Female NPT outlet, this ASME Section IV certified valve is factory set at 50 PSI to provide critical overpressure protection. With a substantial 3,384,000 BTU capacity, it manages high-output systems by utilizing a silicone seat and a diaphragm isolated spring chamber, which prevents corrosive water contact with the alloy steel plated spring. The ASTM B584 Bronze body ensures long-term durability in demanding mechanical rooms, while the elevated valve seat design facilitates positive drainage away from the seating area. For contractors requiring National Board capacity certified performance, this Apollo 10-600 series valve delivers reliable pressure relief up to a maximum temperature of 250°F, making it the standard choice for professional HVAC system diagnostics and boiler safety upgrades.

• High BTU Capacity: Rated at 3,384,000 BTU/hr to support large commercial and residential boiler systems.
• Durable Construction: Features a robust ASTM B584 Bronze body and corrosion-resistant internal components.
• Engineered Seal: The silicone seat provides a tight seal and excellent heat resistance up to 250°F.
• Spring Protection: A fabric-reinforced molded diaphragm isolates the spring from the media to prevent scale and corrosion.
• Code Compliance: ASME Section IV and National Board certified for strict adherence to safety regulations.

What is the discharge capacity of the 10-606-10?
This specific model is certified for a 3,384,000 BTU/hr capacity at its 50 PSI set pressure.

Can this valve be used for steam applications?
No, the 10-600 series is designed and ASME Section IV certified specifically for hot water heating boilers and supply systems, not for steam service.

What is the benefit of the diaphragm in this relief valve?
The diaphragm acts as a barrier, ensuring that the water never reaches the spring chamber, which prevents mineral buildup and ensures consistent pressure relief valve performance.
