Description
The Trane VAL19238 Expansion Gear Valve D2.4 is a refrigerant flow control component used in cooling systems to regulate the amount entering the evaporator circuit. It adjusts opening position based on pressure and temperature changes within the system, supporting maintaining stable operating conditions and consistent cooling output. Mounted in compatible split and packaged equipment, it works within the refrigeration loop between the liquid line and evaporator section. This valve supports efficient heat exchange, balanced system performance, and operation in residential and light commercial air conditioning in HVAC systems.
