Description
The Trane VAL08719 Thermostatic Expansion Valve is a refrigerant metering part designed to regulate the flow of R-410A into the evaporator coil based on system demand. With a 3-ton capacity and 3/8-inch inlet by 1/2-inch outlet connections, it controls superheat by adjusting the amount of refrigerant entering the coil, helping prevent liquid from reaching the compressor. It is installed at the evaporator inlet, where it responds to temperature changes for accurate flow control. In HVAC systems this valve helps regulate refrigerant flow evenly, promoting effective heat exchange and stable cooling operation.
