Product Description

The HEATCONTROLLER664850R 664850R is a 3/8 inch service valve designed for use in refrigerant line service applications. Service valves of this type provide a means of isolating refrigerant flow within a system, allowing technicians to recover, charge, or check pressures without fully decommissioning the equipment. This valve is a direct OEM-style replacement part and is installed by licensed HVAC technicians working on split systems or packaged units where refrigerant circuit access is required.

This service valve is suited for residential and light commercial HVAC applications where a 3/8 inch connection size is specified. It is typically found on the suction or liquid line of a refrigerant circuit and is used during routine service, system commissioning, or component replacement. Technicians installing this valve should verify connection size and thread compatibility with the existing system before installation.
