Trane VAL3858 Thermal Expansion Valve 3/8 X 1/2 R-22 1Ton 30" Capillary

The Trane VAL3858 Thermal Expansion Valve (TXV) is an essentialcomponent in your Trane air conditioning system, A refrigerant flow control valve that learns from temperature and adapts for the specific job of cooling smaller loads. Unlike simple on/off valves the TXV is a essentialcomponent in the cooling process. In the case of the TXV, a thermal sensor bulb is attached to the valve by a long, thin capillary tube and regulates the amount of refrigerant that enters the evaporator coil by sensing its temperature. This has ODM (Open Die Molding) interfaces for connection with a piping arrangements and non-bleed to ensure accurate control of the refrigerant.
