Mueller Refrigeration aq17860c Cyclemaster Ball Valve Standard with Access Port 3/8 Inches

Product Description

The Mueller Refrigeration AQ17860C is a Cyclemaster ball valve designed for refrigeration and HVAC systems that require reliable shutoff and service access in a single compact fitting. This standard ball valve features a built-in access port, which allows technicians to perform pressure checks, charge refrigerant, or evacuate the system without removing the valve or adding extra Schrader fittings to the line set. That built-in service port saves installation time and reduces potential leak points in the refrigerant circuit.

The AQ17860C uses a 3/8 inch connection size, making it compatible with common suction and liquid line sizes found in residential and light commercial refrigeration equipment. The valve port measures 0.50 inches, and the flow coefficient Cv is rated at 4.30, which supports adequate refrigerant flow in properly sized systems. The Kv value is 4, aligning with international flow rating standards for service technicians working across different markets.

This valve is rated for a maximum allowable pressure of 775 psi, or 53 bar, which covers the high-side pressures found in R-410A, R-404A, R-22, and other common refrigerants. The operating temperature range runs from -40 degrees Fahrenheit to 300 degrees Fahrenheit, so it performs reliably in both low-temperature freezer applications and high-ambient outdoor condensing unit environments. The valve body includes a drilled and tapped feature as a standard part of the product offering, which is noted in the reference indication. A seal cap kit, part number A 17842, is available separately for service and maintenance needs. HVAC technicians, refrigeration mechanics, and commercial service contractors rely on Cyclemaster valves for consistent performance in demanding field conditions.

• Built-in access port allows pressure testing and refrigerant service without extra fittings
• Rated to 775 psi maximum allowable pressure for compatibility with modern high-pressure refrigerants
• Wide operating temperature range from -40 degrees Fahrenheit to 300 degrees Fahrenheit suits both freezer and outdoor applications

Product Highlights

The Mueller Refrigeration AQ17860C Cyclemaster ball valve combines standard shutoff function with an integrated access port, reducing installation complexity and leak risk in refrigeration and HVAC line sets. Its high pressure rating and broad temperature range make it a dependable choice for residential and commercial refrigeration service work.
