Description
The Trane VAL21652 Thermostatic Expansion Valve BBIYE-7-CP-B30 is a refrigerant metering part mounted on HVAC in order to regulate the amount of refrigerant to flow into the evaporator coil based on the amount of thermal load and superheat. It is located on the liquid pathway between the evaporator and the condenser to measure temperature and pressure at the evaporator outlet to control the flow of refrigerant to make sure that the heat exchange is optimum. It operates in the HVAC system to make the delivery of refrigerant and the supply part of the cooling process.
