Description
The Lennox 60M98 Thermal Expansion Valve (TXV) is a refrigerant metering part used in R-410A HVAC systems to control the flow of liquid into the evaporator coil. It automatically adjusts flow based on load by sensing temperature and pressure changes at the outlet, supporting maintaining proper superheat levels. Mounted in air conditioning and heat pump systems, it ensures efficient cooling performance, protects the compressor from liquid refrigerant return, and supports stable system operation under varying load conditions. This valve is a key component in maintaining correct refrigeration cycle balance and overall system efficiency.
