Description
The Copeland Comfort Control (Alco) 066664 5-Ton Thermal Expansion Valve R410A regulates refrigerant flow in HVAC systems by responding to temperature and pressure changes at the evaporator inlet. It maintains controlled superheat conditions to support stable cooling performance under varying load requirements. The valve operates as a metering part within air-conditioning and refrigeration units, ensuring proper refrigerant distribution across the system. Installed in cooling circuits, it helps maintain operational balance, supports compressor stability, and contributes to consistent heat exchange efficiency in residential and commercial applications.
