Description
The International Comfort Products 1174451 is an OEM thermostatic expansion valve (TXV) engineered for reliable refrigerant metering in residential and light-commercial cooling systems. Designed specifically for use with R-22 refrigerant, this valve is sized to handle 2- to 3-ton system capacities, making it an ideal direct replacement for ICP, Heil, Tempstar, Arcoaire, and other International Comfort Products brand equipment that share this component.
How a TXV Works
A thermostatic expansion valve regulates the flow of liquid refrigerant into the evaporator coil by sensing suction-line temperature and pressure. By maintaining the proper superheat at the evaporator outlet, the TXV maximizes heat-transfer efficiency, protects the compressor from liquid slugging, and keeps the system operating within design parameters across varying load conditions.
