Mueller A17936 Check Valve

The Mueller A17936 is a professional-grade 1/2" Magnetic Check Valve engineered for heavy-duty refrigeration and air conditioning systems. Featuring a hermetically formed solid copper body, this valve ensures zero leak potential while maintaining structural integrity under high-pressure conditions. Unlike traditional spring-loaded variants, its magnetic closure mechanism provides a more positive seal with a significantly lower pressure drop, making it ideal for liquid, suction, and hot gas lines. The internal assembly utilizes DuraForm Technology to prevent overheating during the brazing process, preserving the 30 mesh stainless steel screen and the teflon seat. This valve is UL/cUL recognized and fully compatible with modern HFC and HCFC refrigerants, including high-pressure R410A. Its sweat connection design includes mechanically formed solder stops for precise fitment in both vertical and horizontal orientations. Designed for reliability, the A17936 supports a maximum working pressure of 800 psi and satisfies the needs of contractors seeking top-tier backflow prevention.

• Magnetic Force Sealing: Provides superior positive isolation compared to spring-loaded check valves, reducing system resistance.
• High-Pressure Tolerance: Rated for up to 800 psi (55 bar), making it suitable for volatile environments and modern high-pressure blends.
• Internal Filtration: Integrated 3 mesh stainless steel screen protects downstream components from debris and prevents valve sticking.
• Hermetic Construction: Spun-copper body design eliminates common leak paths associated with threaded or multi-piece housings.
• Broad Temperature Range: Operational capacity from -40°F to 300°F (-40°C to 149°C) ensures stability in extreme thermal cycles.

Common Questions

Is the Mueller A17936 compatible with R410A refrigeration systems?
Yes, this valve is rated for a maximum working pressure of 800 psi, which safely exceeds the operational demands of R410A systems and various other HFC/HCFC refrigerants.

Can I install this valve in a vertical line?
Absolutely. The magnetic closure allows for multi-orientation installation, including vertical and horizontal positions, without sacrificing sealing reliability or increasing pressure differential benchmarks.

How do I prevent damage to the internal components during soldering?
The valve is built with DuraForm Technology to insulate critical components. However, it is standard professional practice to use a wet rag or heat-sink paste on the solid copper body to avoid exceeding temperature limits during installation.
