Lennox 91M01 Thermal Expansion Valve R22 6 Ton

The Lennox 91M01 Thermal Expansion Valve (TXV) is an essential control part intended for refrigerant flow control in Lennox air conditioning and refrigeration systems having a 6-ton cooling capability. Being a core part of system efficiency this valve is made from metals particularly brass. The 91M01 TXV controls refrigerant flow depending on the temperature inside the evaporator coil. This allows the coil to get the right amount of refrigerant the absorbs heat and produces the right amount of cooling effect. This specific TXV is intended for use with R22 refrigerant, a refrigerant still used in many older heating and cooling systems.
