Description
The Trane VAL08634 Thermostatic Expansion Valve with mechanical fittings regulates refrigerant flow into the evaporator by responding to temperature and pressure conditions at the outlet. It uses a sensing bulb and diaphragm assembly to adjust the valve opening maintaining proper superheat during operation. Within HVAC systems such as split air conditioners and packaged units, it enables accurate refrigerant control for effective heat exchange. Installed between the liquid line and evaporator, it supports stable cooling output, balanced operation, and consistent system performance under varying load conditions.
