Lennox Thermostatic Expansion Valve

The Lennox Thermostatic Expansion Valve (TXV, also called a thermostatic expansion valve or A/C expansion valve) is a metering device for residential and light commercial heating and cooling systems. It controls how much liquid refrigerant flows into the evaporator coil. This helps the system run efficiently and keeps the coil properly fed under changing load conditions.

Key Features:

• Senses evaporator outlet conditions and adjusts refrigerant flow to match the cooling load
• Helps maintain proper superheat for efficient operation and compressor protection
• Sweat-type ODF (outside diameter female) connections for brazed installation
• Designed as a replacement part for Lennox air conditioning and heat pump systems
• Available in multiple capacities and connection configurations within the product line

Choose the variant that matches your system's capacity and connection requirements. Use a Lennox TXV to help restore stable refrigerant control and dependable cooling performance.
