Conbraco 10-604-34 Relief Valve

The Conbraco 10-604-34 Relief Valve is a high capacity pressure relief valve engineered specifically for high-output hot water boiler systems and storage tanks. This model features 3/4" Female NPT inlet and outlet connections, with a factory set pressure of 150 PSI. Built with a heavy-duty bronze body and stainless steel springs, it provides a 3,116,000 BTU/hr capacity, making it essential for large-scale hydronic heating applications. The Conbraco 10-604-34 is a direct cross-reference for the RVW6034150, ensuring zero-clearance compatibility for field replacements. Its high-flow design prevents over-pressurization during thermal expansion, maintaining the structural integrity of the heat exchanger. Designed for easy maintenance, the top-guided stem and non-stick PTFE-coated disc seating prevent scale buildup, ensuring reliable popping action and consistent reseating in demanding commercial environments.

Technical FAQ

What is the difference between the Conbraco 10-604-34 and the RVW6034150?
These parts are functionally identical. The 10-604 series is the manufacturer's designation, while the RVW number is often used in distribution; both share the same 150 PSI set point and 3/4" NPT dimensions.

Does this valve support steam applications?
No, this is a hot water high-capacity relief valve specifically designed for water systems. Use an ASME Section I or IV steam safety valve for steam boiler applications.

Why is the BTU rating significant for this relief valve?
The 3,116,000 BTU rating must equal or exceed the gross output of the boiler to ensure the boiler relief valve can discharge enough volume to prevent a pressure excursion.
