Conbraco 10-616-09 Valve
Operating as a critical safety component for high-output hydronic systems, the Conbraco 10-616-09 Valve is a high-capacity pressure relief valve engineered specifically for ASME Section IV hot water heating boilers. This industrial-grade safety relief valve features a robust ASTM B584 bronze body construction and a silicone seat, ensuring consistent performance at a fixed set point of 45 PSI. With a massive 3,656,000 BTU capacity, it effectively manages thermal expansion and protects pressurized vessels from catastrophic over-pressurization. The design incorporates a 1-1/4" Female NPT inlet and an oversized 1-1/2" Female NPT outlet to facilitate rapid discharge during lift events. A diaphragm-isolated spring chamber keeps the alloy steel spring free from mineral scaling and corrosive water contact, while the elevated seat design promotes positive drainage. This National Board certified relief valve is essential for contractors maintaining large-scale commercial boilers or high-volume hot water supply systems where ASME compliance and high-flow reliability are non-negotiable field requirements.
Key Benefits- Internal Protection: Features a fabric-reinforced molded diaphragm that isolates the spring from water contact, preventing corrosion and mechanical sticking.
- Oversized Discharge: The 1-1/2" outlet allows for higher flow volumes compared to standard relief valves, crucial for high BTU hot water systems.
- National Board Certified: Fully compliant with ASME Section IV regulations, ensuring the valve meets 90% of actual capacity at 10% overpressure.
- Thermal Resilience: Rated for temperatures up to 250°F, making it suitable for high-demand heating applications.
- Field Serviceability: Equipped with a steel lift lever for required manual testing and verification of the 45 PSI set pressure.
What is the correct mounting orientation for this relief valve?
To ensure proper operation and drainage, this valve must be mounted in a vertical, upright position directly to the boiler or pressure vessel. Never install a shut-off valve between the boiler and the relief valve.
Can I use schedule 80 pipe for the discharge line?
No. You must use schedule 40 pipe for the discharge line. The internal diameter must remain equal to or larger than the 1-1/2" valve outlet to prevent backpressure that could interfere with the valve's lifting capacity.
How often should a try-lever test be performed?
For hot water service, a manual lever test should be performed at least once every six months to ensure the seat is not fouled by sediment. The system should be near operating pressure during this test to flush the seating surface effectively.
