Conbraco 10-616-07 Valve

As a seasoned contractor, you know that protecting high-output hydronic systems requires more than just a standard relief valve. The Conbraco 10-616-07 Valve, also known as the Apollo 10-600 series, is an ASME Section IV certified powerhouse designed specifically for large-scale hot water heating boilers. With a massive 3,343,000 BTU capacity and a factory set pressure of 40 PSI, this valve is engineered to handle the thermal expansion and over-pressurization risks common in commercial boiler rooms. The 10-616-07 features a 1-1/4" Female NPT inlet and an oversized 1-1/2" Female NPT outlet, ensuring rapid discharge when limits are reached. Its bronze body construction and silicone seat provide excellent resistance to mineral buildup and corrosion, while the diaphragm-isolated spring chamber keeps the mechanical components away from the water stream to prevent scaling. Rated for temperatures up to 250??F, this high capacity pressure relief valve is the reliable choice for maintaining the safety and integrity of commercial hydronic systems.

• ASME Section IV Certified: National Board capacity certified to meet strict safety codes for hot water supply systems.
• High BTU Rating: Rated for 3,343,000 BTU/hr to protect even the largest commercial heating boilers.
• Enhanced Durability: Features an ASTM B584 bronze body and an EPDM/silicone soft seat for a tight seal and long-term reliability.
• Corrosion Protection: The fabric-reinforced molded diaphragm isolates the spring from the process media at all times.
• Superior Drainage: Designed with an elevated seat to facilitate water drainage away from the seat area.

• What is the difference between the 10-616 and 10-606 models? The 10-616 model features an expanded 1-1/2" outlet for higher discharge capacity, whereas the 10-606 typically has a standard 1-1/4" outlet.
• Can this valve be used for steam applications? No, this is a Section IV valve specifically rated for water service in heating boilers and supply systems; it is not for steam boiler use.
• What mounting orientation is required? For optimal performance and code compliance, these valves must be installed in a vertical upright position.
