Mueller Streamline a13183 Angle Valve 1/2 Inch Refrigeration

Product Description

The MUELLER STREAMLINE a13183 is a packed line angle valve with backseating designed for refrigeration service. The forged brass body provides durability under demanding operating conditions, and the corrosion-resistant stem is suited for use with refrigerants and other industrial fluids. This valve is rated for a maximum abnormal pressure (MAP) of 700 psig and a continuous operating temperature (COT) range of -40 degrees F to 300 degrees F. It is compatible with all CFC, HCFC, and HFC refrigerants and oils. Licensed refrigeration and HVAC technicians typically install this valve as part of a refrigerant line service or system commissioning job.

This angle valve is used in refrigeration and air conditioning systems where a reliable line shutoff or service valve is required. The backseating feature allows packing replacement without fully shutting down the system, which is a practical advantage in commercial and industrial refrigeration applications. The 1/2 inch configuration suits common suction and liquid line work in both light commercial and residential refrigeration equipment.
