Trane VAL7237 Thermal Expansion Valve 3/8 X 5/8 R-22 2Ton 30" Capillary

The Trane VAL7237 Thermal Expansion Valve (TXV) is one of the necessary parts of your Trane air conditioning system, a valve that controls refrigerant flow by temperature, is better for mid-size cooling applications. Unlike the simple on/off valves, the TXV has a active role in cooling. The TXV is equipped with a thermal sensor bulb that is connected to the device through a long, thin capillary tube, which measures the temperature of the refrigerant and regulates the amount of the substance that enters the evaporator coil. This will make sure that the coil can effectively absorb the heat without frosting up and causing other problematic issues to your whole system. In particular, the Trane TXV tends to be installed in air conditioners with the 2-tonnage.
