Description
The Trane VAL11915 Thermostatic Expansion Valve is a refrigerant metering Unit that regulates flow into the evaporator, maintaining proper superheat and stable operation within HVAC systems. Designed for 6-ton R410A applications with 1/2″ x 5/8″ connections and a 60°C rating, it responds to temperature and pressure changes through a sensing bulb and internal diaphragm to adjust the valve opening. This allows refrigerant to be delivered according to system load. Connected along the liquid line near the evaporator coil, it is fitted into the piping during setup, enabling controlled refrigerant flow and consistent cooling performance.
