Conbraco 10-614-25 Valve

The Conbraco 10-614-25 is a professional-grade high capacity pressure relief valve, specifically engineered for the protection of boilers and hot water heating systems. This ASME Section IV certified valve provides a critical safety layer for commercial and industrial hydronic equipment, featuring a high-volume 3,096,000 BTU capacity to prevent catastrophic failure from overpressure. Designed with a 3/4" Female NPT inlet and an expanded 1" Female NPT outlet, it maximizes discharge flow for high-demand applications. The rugged ASTM B584 bronze body construction ensures long-term resistance to corrosion in harsh environments, while the silicone seat provides a reliable, tight seal. Maintenance is simplified through a diaphragm-isolated spring chamber, which keeps the plated alloy steel spring dry and free from mineral buildup. Pre-set at 125 PSI with a maximum temperature rating of 250°F, this Apollo RVW61 series valve is the standard choice for technicians requiring reliable thermal expansion protection and code-compliant safety in large-scale heating plants.

• ASME Section IV Certified: National Board capacity certified to meet stringent safety codes for hot water heating boilers.
• High BTU Displacement: Delivering a 3,096,000 BTU/hr rating, making it suitable for large commercial boiler banks.
• Superior Material Durability: Constructed with a high-strength bronze body and a silicone seat for positive shut-off and heat resistance.
• Isolated Spring Design: A fabric-reinforced molded diaphragm protects the internal spring from water contact, preventing scale and corrosion.
• Optimized Flow Path: Features an expanded 1-inch outlet to reduce backpressure during emergency discharge events.

What is the maximum operating temperature for this relief valve?
The valve is rated for a maximum temperature of 250°F (121°C), suitable for most high-temperature hydronic heating systems.

Does the 10-614-25 require field adjustment?
No, this unit comes factory set at 125 PSI. While the 10-600 series is available in various settings, this specific model is calibrated for 125 PSI system protection.

Can this be used for steam applications?
This specific model is designed and certified for hot water service (ASME Section IV Heating Boilers). Always verify your medium requirements against the ASME certification plate on the valve body.
