Description
The Trane VAL04407 14.9-Ton Thermostatic Expansion Valve 0.875″ x 1.375″ is designed to regulate refrigerant flow into the evaporator coil based on load conditions. It is typically installed in the liquid line of air conditioning or heat pump systems, where it meters to maintain optimal superheat and prevent coil flooding. By adjusting the amount entering the evaporator the valve ensures efficient heat exchange, stable cooling performance, and proper pressure control. This component supports reliable operation and energy-efficient performance in residential and commercial HVAC systems.
