Conbraco 10-104-10 Relief Valve

The Conbraco 10-104-10 Relief Valve (Apollo RVW10 Series) is a high-capacity safety solution engineered for ASME Section IV hot water boilers and hydronic heating systems. Built with a rugged ASTM B584 Bronze body and nozzle, this valve ensures reliable overpressure protection for commercial and residential applications. It features a 3/4 inch Male NPT inlet and a 1 inch Female NPT outlet, facilitating a high-volume discharge rate. Factory-set at 50 PSI, it supports a significant 1,035,000 BTU/hr capacity, making it suitable for large-scale heating equipment. The internal stainless steel spring provides consistent seat pressure, while the EPDM seat ensures a tight seal up to a 250°F maximum temperature. Designed to prevent system failure due to thermal expansion or control malfunction, this hot water pressure relief valve is a critical component for maintaining hydronic system integrity and compliance with national safety codes.

• ASME Section IV Certified: Validated capacity performance for high-output heating systems.
• Corrosion-Resistant Construction: Durable bronze body and stainless steel internals provide longevity in harsh hydronic environments.
• High BTU Rating: Manages up to 1,035,000 BTU/hr, allowing for use in substantial commercial boiler setups.
• Precise Pressure Management: Factory-calibrated to 50 PSI to ensure immediate response during overpressure events.

• What is the difference between the 10-100 and 10-300 series? The 10-100 series includes the 3/4" male inlet option (like the 10-104-10), whereas the 10-300 series typically features female-to-female connections.
• Is this valve suitable for steam applications? No, the 10-104-10 is specifically rated for hot water heating boilers and hydronic systems under ASME Section IV.
• Can the set pressure be adjusted in the field? To maintain ASME certification and safety standards, these valves are factory-set and should not be tampered with or adjusted by the installer.
