Conbraco 61-507-01 Check Valve

The Conbraco 61-507-01 is a professional-grade 1 1/2-inch FNPT check valve engineered for critical backflow prevention in hydronic heating and industrial fluid systems. Built with a rugged cast bronze body (ASTM B584), this in-line check valve features an EPDM soft seat that provides a bubble-tight shut-off, significantly reducing noise and vibration compared to standard metal-seated valves. The spring-actuated design ensures rapid seating and prevents water hammer, while the center-guided stem maintains precise alignment over high-cycle operations. Rated for 400 PSI CWP (Cold Working Pressure) and temperatures up to 250°F, this Apollo 61-500 series valve is ideal for low-flow applications where reverse flow protection is essential. The straight-through flow design maximizes efficiency and minimizes pressure drop across the line. This domestic soft seat check valve is 100% factory tested to meet rigorous HVACR and plumbing standards, providing contractors with a reliable solution for liquid and gas media management.

• Bubble-Tight Seal: The EPDM soft seat ensures a 100% leak-proof shut-off, protecting sensitive components from reverse flow.
• High Pressure Rating: Rated for up to 400 PSI non-shock cold working pressure for demanding industrial environments.
• Spring-Loaded Action: Features a stainless steel spring for fast closing, allowing for installation in both horizontal and vertical (upward flow) positions.
• Durable Construction: Heavy-duty bronze check valve body offers superior corrosion resistance and longevity in hydronic systems.
• Low Cracking Pressure: Standard 0.5 PSI cracking pressure allows for efficient flow activation even in lower-pressure systems.

Can this valve be used for steam applications?
While the bronze body is robust, the EPDM seat is rated for a maximum temperature of 250°F. For high-pressure saturated steam, a metal-seated or RPTFE ball-cone valve from the 61-100 series is typically recommended.

Is the Conbraco 61-507-01 lead-free?
This specific model is the standard bronze version. For potable water systems requiring lead-free compliance, the 61LF series equivalent should be utilized.

What is the recommended installation orientation?
This spring-actuated valve functions reliably in horizontal runs or vertical lines, provided the flow is in the upward direction. Ensure a minimum of 10 pipe diameters of straight pipe exist upstream to prevent turbulence issues.
