Description
The Trane VAL09742 Thermostatic Expansion Valve with Mechanical Fittings is used to control the supply of refrigerant into the evaporator depending on the load conditions in HVAC systems. It measures the temperature of the liquid line and changes the expansion orifice to ensure the superheat is kept at the right temperature to heat transfer in the cooling cycles. It is fitted in the refrigeration circuit between the condenser and evaporator and operates with the controls and sensors of the refrigerant flow. The constant temperature in residential or commercial air-conditioning systems.
