Conbraco 61-104-01 Check Valve

For mid-sized hydronic and steam systems, the Conbraco 61-104-01 Check Valve provides a rugged, inline solution to prevent backflow and protect upstream equipment. This 3/4" female NPT spring actuated bronze CVB ball cone check valve is built with a heavy-duty ASTM B584 bronze body and a chemically resistant RPTFE ball cone, ensuring a tight seal even in demanding chemical service or saturated steam applications up to 125 psi. The spring-loaded design eliminates the need for specific radial alignment, allowing for versatile horizontal or vertical upward flow installation. With a cracking pressure of 0.5 psi and a straight-through flow pattern, this valve minimizes pressure drop while maintaining high flow efficiency. For veteran contractors, the Apollo valve series 61-100 is a standard for reliability, offering a 400 psi CWP rating and the ability to withstand temperatures up to 406°F. This domestic, USA-made check valve is 100% factory tested to handle the rigors of industrial HVACR environments.

• Corrosion Resistant Construction: High-grade bronze body and stainless steel spring withstand harsh environments.
• Directional Versatility: Suitable for both vertical (upward) and horizontal piping layouts.
• Low Cracking Pressure: Opens at just 0.5 psig to minimize system drag and energy loss.
• Tight Liquid Shut-off: The RPTFE ball-cone design ensures a reliable bubble-tight seal against backflow.
• Simplified Maintenance: Center-guided ball design ensures consistent seating and reduces mechanical wear.

Can this valve be used with reciprocating pumps?
It is not recommended for applications with reciprocating pumps or high-frequency vibrations, as turbulence can lead to premature wear of the internal components.

What is the maximum temperature rating for this model?
The valve is rated for a maximum temperature of 406°F, making it suitable for high-heat saturated steam and industrial liquid service.

Does this valve require a minimum straight pipe run?
For optimal performance and to prevent chatter, it is recommended to install at least 10 diameters of straight pipe upstream of the valve inlet.
