Lennox 59W21 Thermal Expansion Valve(TXV) 3/8" X1/2" ODF 8-Ton 30" Cap

The Lennox 59W21 is a Thermal Expansion Valve an essentialpart of HVAC systems that controls refrigerant expansion. It is made of brass and it dimensions are 3.1 Inches length by 4.5 Inches height by 3.8 Inches width. Due to change in temperature, the TXV regulates the amount of refrigerant admitted into the evaporator coil accurately. This also maximizes system efficiency because it produces the appropriate phase of the refrigerant for carrying heat out of the room. TXVs can be located in different HVAC equipment such as heat pumps and air conditioners . The TXV ensures that either too little or too much refrigerant is not circulated hence providing efficient cooling and less energy consumption for the HVAC system.
