Description
The First Company 9EVR410-5 thermal expansion valve kit is a refrigerant metering component used in HVAC systems operating with R410A. It regulates refrigerant flow into the evaporator coil by responding to temperature and pressure changes at the outlet, maintaining proper superheat control during system operation. It is commonly placed in air handler and fan coil assemblies used in residential and light commercial HVAC setups. This kit supports systems in the 3.5 to 5 ton range and is integrated into cooling or heat pump configurations. It plays a key role in stabilizing evaporator performance and maintaining consistent cooling cycle efficiency.
