Mueller A17520 Service Valve

The Mueller A17520 Service Valve is a heavy-duty brass compressor valve designed for critical flow control in commercial refrigeration and air conditioning systems. Engineered as a 5/8" 45-degree flare double port component, this valve facilitates seamless gauge manifold attachment and system evacuation. With a design pressure (DP) of 700 psig (48 bar), it meets the rigorous demands of high-pressure HVACR refrigeration cycles and is compatible with a wide range of CFC, HCFC, and HFC refrigerants. The Mueller Streamline A17520 features asbestos-free packing and is 100% factory tested to ensure reliable performance under extreme conditions, including a continuous operating temperature range of -40°F to 300°F. Technical professionals choose this double port service valve for its maximum flow design, which significantly reduces pressure drop during operation. This HVAC replacement part serves as a direct OEM solution for technicians seeking a bolt-on compressor valve that maintains vacuum integrity and system efficiency.

• High-Pressure Capability: Rated for a maximum abnormal pressure of 700 psig, making it suitable for modern high-pressure refrigerants.
• Optimized Flow Design: Engineered with internal openings that maximize refrigerant flow while minimizing restrictive pressure drops.
• Durable Construction: Forged brass body provides superior strength and corrosion resistance in harsh mechanical environments.
• Temperature Resilience: Sustains reliable operation across a broad thermal spectrum from -40°C to 149°C.
