Lennox 25C02 TXV Valve

Lennox 25C02 TXV Valve

Lennox

The Lennox 25C02 is a thermostatic expansion valve (TXV) designed for compatible R-410A air conditioning and heat pump systems in the 3.5–5 ton capacity range. This refrigerant metering component regulates refrigerant flow into the evaporator coil based on operating conditions and helps maintain proper evaporator superheat.

The Lennox R-410A TXV valve responds to changes in evaporator outlet temperature, adjusting refrigerant flow to match system demand. Proper refrigerant metering supports evaporator performance and helps prevent excessive liquid refrigerant from returning to the compressor.

When replacing an existing HVAC expansion valve, technicians should verify the equipment model, refrigerant type, capacity range, connection sizes, and valve configuration. Correct installation, sensing bulb placement, and system charging procedures are essential for proper operation.

The Lennox 25C02 is intended for compatible Lennox HVAC equipment requiring this specific 3.5–5 ton refrigerant expansion valve.
