TVX & Control Valves

TVX & Control Valves

TXV and control valves are responsible for controlling the flow of liquid refrigerant into the evaporator of an air conditioning (A/C) system. You can find the right valve for your system by entering your registration number and clicking OK on the tool above.
A vital component of your car's A/C system is the thermal expansion valve, otherwise known as a TXV, or simply TX, valve. For your A/C to work, the evaporator must receive enough refrigerant to be able to create the cool air that's pumped into your car.

The TXV valve works by way of a pin that, depending on the settings you choose on your A/C system, restricts the flow of the liquid. When you turn your A/C on, the valve pin allows the appropriate amount of refrigerant to enter the evaporator, which is where your cool air is formed.

If you are not receiving any cool air from your A/C system, it is likely that your TXV or control valve is faulty and needs replacing.
