Trane VAL8785 Thermal Expansion Valve(TXV) 1/2 x 7/8"

The Trane VAL8785 Thermal Expansion Valve is special to the Trane HVAC system used in heat pumps. It monitors refrigerant temperature using a temperature-sensing bulb. The TXV is based on this temperature and adjusts the opening of a valve to control the volume of refrigerant evaporator coil. This extremely accurate control assures optimum cooling efficiency and eliminates evaporator coil icing. Made from durable materials to stand up to the pressures inside the system at 90 PSI the Trane tends to be a lot more sturdy than other screw chillers as a result.
