Conbraco Industries 61-103-01 Check Valve

The Conbraco Industries 61-103-01 is a high-performance 1/2" FNPT check valve engineered for critical backflow prevention in commercial and industrial piping sectors. Built with a heavy-duty bronze body (ASTM B584), this spring-actuated check valve utilizes the proprietary Ball Cone design to ensure a bubble-tight seal even in low-pressure conditions. Unlike standard swing checks, the 61-103-01 features an RPTFE (reinforced Teflon) cone that offers superior corrosion resistance and chemical compatibility, making it a reliable choice for saturated steam service up to 125 psi or liquid applications up to 400 psi CWP. Its inline check valve configuration supports versatile installation in both horizontal and vertical upward flow orientations. The stainless steel spring provides a consistent 0.5 psi cracking pressure, effectively minimizing water hammer and protecting sensitive downstream equipment. This domestic-made component is a standard for technicians requiring durable Apollo valves for hydronic heating and chemical processing systems.

• Exceptional Sealing: The RPTFE Ball Cone provides a tight shut-off for liquid media, outperforming metal-seated alternatives.
• High-Temperature Resilience: Rated for temperatures up to 406°F, ideal for steam system integration.
• Versatile Installation: The spring-loaded mechanism allows for reliable operation in any orientation with upward flow.
• Straight-Through Flow: Optimized internal geometry ensures low pressure drop and maintains system efficiency.
• Industrial Durability: Cast bronze construction resists dezincification and harsh environmental conditions.

Can this valve be used with reciprocating air compressors?
No, this series is not recommended for reciprocating air compressor service due to potential vibration-induced wear.

What is the flow coefficient for the 1/2" model?
The 61-103-01 has a flow coefficient (Cv) of 1.4, providing a balance of flow capacity and backflow protection.

Is this valve suitable for potable water?
This specific model is not lead-free and should be used primarily for HVACR, steam, and industrial chemical applications.
