Description
The Trane VAL11522 4-Ton Expansion Valve 0.375″ ODF Inlet is a thermostatic component, used to regulate refrigerant flow into the evaporator coil in air conditioning, and heat pump systems. It is typically installed in the liquid line, where it meters refrigerant based on system load conditions to maintain proper superheat and ensure efficient heat transfer. This component plays a key role in controlling cooling performance preventing evaporator flooding or starvation, and supporting stable system operation. It is commonly used in residential and light commercial split systems requiring precise refrigerant control for reliable cooling performance.
