Description
The Copeland Comfort Control (Alco) 064991 Check Valve regulates the direction of flow of the refrigerant by permitting flow in one direction but not in the opposite direction. A 1-1/8″ ODF connection size in HVAC systems it provides adequate flow control to refrigeration circuits. It works by using an internal mechanism that opens under forward pressure and closes when flow reverses, maintaining directional integrity. It is installed in refrigerant lines, and it interfaces with system piping to direct flow. Its operation prevents backflow system efficiency, and ensures stable operation.
