Four Seasons A/C Expansion Valve TXV Thermostatic Expansion Valve

The Four Seasons A/C expansion valve, also called a thermostatic expansion valve (TXV) or A/C metering device, controls how much liquid refrigerant enters the evaporator in a vehicle's air conditioning system. It helps the system cool efficiently under changing heat loads and engine speeds.

Key Features:

• Meters refrigerant flow to the evaporator to help maintain consistent cooling performance
• Helps keep the evaporator at a suitable temperature and reduces the risk of evaporator freeze-up
• Helps protect the compressor by limiting liquid refrigerant return
• Designed to match the form, fit and function of the original equipment valve
• Made by Four Seasons, a long-established supplier of aftermarket A/C and engine cooling components

Replacing a worn or stuck expansion valve can help address weak cooling, uneven vent temperatures, or evaporator icing. Whenever the refrigerant circuit is opened, replace the receiver/drier or accumulator and evacuate and recharge the system to the vehicle manufacturer's specifications.
