Description
The Trane VAL09406 Thermostatic Expansion Valve (TXV) W/Mechanical is a refrigerant metering component that regulates liquid entering the evaporator coil based on load conditions in cooling and heat pump equipment. It is used in air conditioning systems where controlled feeding is necessary for stable heat exchange and compressor protection. It runs through a sensing bulb and diaphragm assembly that respond to temperature and pressure variations, adjusting internal flow to maintain correct superheat and prevent fluid return to the compressor. Mounted within HVAC systems, it connects between the liquid line and evaporator inlet to control cold air distribution and promote efficient transpiration.
