Description
The Lennox 27P55 Expansion Check Valve is a refrigerant flow control component used in HVAC systems to regulate the movement of refrigerant within the cooling circuit. It combines expansion control with a check operation to manage flow direction and support proper refrigerant distribution between system sections. Commonly applied in air conditioning and heat pump equipment it is installed within the refrigerant line where it interacts with evaporator and condenser pathways. As part of the refrigeration assembly it supports controlled refrigerant flow and prevents reverse movement within the circuit during operation.
