Description
The Trane VAL09228 Thermostatic Expansion Valve with Mechanical Fitting regulates refrigerant entering the evaporator section of an HVAC systems. Its thermostatic mechanism adjusts the refrigerant passage according to sensed operating conditions, controlling flow through the expansion system. The valve works within the refrigeration circuit between the liquid line and evaporator coordinating refrigerant delivery with evaporator demand. The integrated mechanical fitting provides the specified connection arrangement for the valve assembly. This component works as metering equipment within the system, managing refrigerant movement at the transition from higher-pressure liquid flow to the evaporator side while controlling operation of the refrigeration cycle.
