Lennox 97M85 Thermal Expansion Valve(TXV) With Check Valve For R410A Unit

The Lennox 97M85 is a Thermal Expansion Valve that requires R410A refrigerant systems in HVAC applications all-inclusive. A TXV is an essentialcontrol device that controls the flow of coolant in an air conditioner or refrigeration system. It works like a flow control element, regulating the pressure and temperature of the evaporator coil. It also provides a check valve to avoid the backflow of refrigerant to maintain the cycle flow. These are enhanced system efficiency, which means less energy is used. It offers control of temperature and maintains the climate of the space. The TXV prevents the system from being flooded or slugged, a condition where too much liquid refrigerant enters the compressor.
