Conbraco 10-608-05 Relief Valve

The Conbraco 10-608-05 is a professional-grade, high-capacity ASME Section IV hot water relief valve engineered specifically for protection against overpressure in large-scale commercial boiler systems. Featuring a 2" Female NPT inlet and a 2" Female NPT outlet, this cast bronze relief valve is factory-set at 30 PSI to ensure precise system safety. With a massive 5,193,000 BTU/hr steam capacity, it manages significant thermal expansion and pressure spikes in high-output hydronic heating applications. The EPDM O-ring seat provides a reliable, bubble-tight seal that resists fouling, while the stainless steel spring ensures consistent set-point repeatability. For contractors performing boiler pressure relief valve replacement, the 10-608 series offers a rugged high-capacity hot water safety valve solution that meets ASME Section IV requirements. Its non-metallic disc-to-soft-seat design prevents galling and sticking, which is critical for long-term reliability in demanding commercial HVACR maintenance environments.

• High BTU Rating: Certified 5,193,000 BTU capacity makes it suitable for large commercial high-volume boilers.
• Durable Construction: Heavy-duty bronze body and stainless steel springs resist corrosion and thermal fatigue.
• Secure Sealing: EPDM soft-seat design prevents constant weeping and ensures a positive shut-off after activation.
• Industry Compliance: Meets mandated safety standards for ASME Section IV pressure vessels.
