Conbraco 10-616-36 Valve
The Conbraco 10-616-36 is a heavy-duty, high-capacity hot water relief valve engineered specifically for ASME Section IV heating boilers and high-output hydronic systems. Featuring a 1-1/4" Female NPT inlet and an expanded 1-1/2" Female NPT outlet, this valve is designed to handle massive thermal expansion and pressure spikes with a certified 10,860,000 BTU/hr capacity. It is factory-set at 160 PSI to provide reliable overpressure protection in demanding commercial and industrial environments.
Built with a corrosion-resistant bronze body (ASTM B584) and a silicone seat, the 10-616-36 ensures a positive seal and high-temperature durability up to 250°F. A critical technical feature for any contractor is the fabric-reinforced molded diaphragm, which isolates the spring from the water flow at all times, preventing scale buildup and ensuring consistent lift. The elevated seat design further assists in draining water away from the seating area to mitigate the risk of mineral deposits and "simmering" during operation.
- ASME Section IV Certified: National Board capacity certified (NB) for high-output hot water boiler protection.
- Maximum Flow Efficiency: The expanded 1-1/2" outlet reduces backpressure, allowing for 90% of actual capacity at 10% overpressure.
- Durable Softgoods: Equipped with a silicone-wrapped seat and stainless steel spring for long-term reliability in harsh water conditions.
- Technician-Friendly Design: Features an integrated lift lever for manual testing and a rugged spring cage for protection against mechanical damage.
Common Questions
What is the maximum operating temperature for the 10-616-36?
This valve is rated for a maximum service temperature of 250°F (121°C), making it suitable for high-temperature hot water supply systems.
Can this valve be mounted horizontally?
No. To comply with ASME codes and ensure proper drainage of the seat area, this valve must be installed in a vertical, upright position directly to a clean tapped opening on the boiler or pressure vessel.
Why does this model have a larger outlet than the inlet?
The expanded 1-1/2" outlet is designed to accommodate the rapid volumetric expansion of water as it flashes to steam or discharges at high velocity, preventing friction loss that could impede the valve's ability to relieve pressure at its full BTU rating.
