Description
The Copeland Comfort Control (Alco) 056021 Expansion Valve regulates refrigerant flow into the evaporator to maintain proper cooling balance. It features 3/8 inch inlet and 1/2 inch ODF outlet connections in an angle configuration, supporting controlled refrigeration metering under typical operating pressures and temperature conditions in HVAC systems. Installed in air conditioning units, heat pumps, and refrigeration circuits, it adjusts flow based on system demand. As part of the coolant control assembly, it helps maintain stable superheat, supports efficient heat exchange, and ensures consistent system performance.
