Mueller A17525 Valve

The Mueller A17525 Valve is a professional-grade 1 1/8 Flange Union Sweat kit designed for high-pressure HVAC and refrigeration service. Engineered as a robust compressor service valve, this component facilitates seamless transitions in both residential and commercial cooling systems. It features a durable brass construction that stands up to extreme operating conditions, maintaining structural integrity within a temperature range of -40°F to 300°F.

This HVAC service valve kit is rated for a maximum pressure of 700 PSI, making it compatible with various modern refrigerants including CFC, HCFC, and HFC blends. The kit typically includes the A-16315 compressor valve, compatible gaskets, and necessary bolts for a complete field installation. With a 2-3/4 inch bolt center and a 1-inch flange thickness, the A17525 is a direct Copeland 998-0510-09 replacement, ensuring critical compatibility for compressor maintenance and system retrofits. The front-seated design and 1/8-inch pipe plug size allow for precise pressure monitoring and isolation during routine recovery or charging procedures.

• Maximum Flow Efficiency: Port geometry is optimized to minimize pressure drop across the fitting.
• High Pressure Rating: Safely handles up to 700 PSIG, suitable for high-pressure refrigerant applications.
• Complete Installation Kit: Includes the valve body, flange gasket, and mounting bolts to reduce downtime.
• Broad Temperature Tolerance: Operates reliably from -40°F for low-temp refrigeration up to 300°F for discharge line service.
• OEM Compatibility: Precision-machined to serve as a reliable replacement for industry-standard compressor valves.

What is the primary application for the Mueller A17525?
This kit is primarily used as a suction or discharge service valve on semi-hermetic compressors, allowing technicians to isolate the compressor for repair or replacement without venting the entire system charge.

Is this valve compatible with HFO refrigerants?
Yes, the brass construction and internal seals are designed for compatibility with CFC, HCFC, HFC, and modern HFO refrigerants and their associated oils.

What are the physical mounting dimensions?
The unit features a 2-3/4 inch bolt center-to-center distance and utilizes a 1-1/8 inch ODS (Outside Diameter Sweat) connection for the refrigerant line.
