Description
The First Company 9EVR454B-4 Thermal Expansion Valve Kit UC Equipment is a flow control component that is optimized to regulate the flow of the refrigerant in the HVAC systems. It operates with R454B refrigerant in A2L system, it varies the supply of refrigerant to the evaporator, because it picks up the load conditions, including temperature and pressure. This compensatory reaction helps in appropriate system operating. Mounted into the refrigerant circuit of unitary equipment, it is an essential element that helps to keep the cooling output and system balance constant.
