Description
The First Company 9EVR22-2 Universal Thermostatic Expansion Valve (TXV) Kit is a refrigerant metering component used in HVAC systems to control liquid refrigerant flow into the evaporator coil. It maintains superheat for stable operation and protects the compressor from liquid refrigerant. Designed for R-22 systems with a capacity range of 18,000 to 37,000 BTU/hr, it is used in residential and light commercial air conditioning and heat pump units. Installed at the evaporator section, it supports efficient heat exchange and consistent cooling performance under changing thermal demands and fluctuating operating conditions.
