Description
The Copeland Comfort Control (Alco) 064290 Thermostatic Expansion Valve manages refrigerant flow within evaporator circuits in residential and commercial HVAC systems. Installed in compatible air conditioning and refrigeration equipment, the valve responds to temperature and pressure changes to maintain proper refrigerant balance during cooling operation. Featuring 3/8-inch by 1/2-inch connections with an HFES1-1/2SZ configuration, the assembly works with designated liquid line and evaporator applications used in compatible refrigerant systems. Positioned within specified refrigerant piping sections, the component supports stable superheat control, consistent evaporator performance, and smooth cooling system operation.
