Description
The Trane VAL12004 Expansion Valve 1.638 1.250 is a refrigerant control component used to control the flow, of refrigerant into the evaporator coil. It works based on pressure, and temperature variation in refrigerant flow to ensure maximum superheat and effective heat absorption in HVAC systems. It is a process based on an internal sensing unit valve opening with changes in conditions. It is installed in the refrigerant line, connected and soldered appropriately, and hooked to the control signals of the system. Both commercial and residential exhibit stable cooling performance, even distribution of refrigerant, and stable operation.
