Carrier EA03SC370 Thermal Expansion Valve

The Carrier EA03SC370 Thermal Expansion Valve is an essential device in HVAC systems intended for R-22 refrigerant. This is essential in controlling the amount of coolant in the system. It uses a bimetallic strip that changes its shape with temperature variation. Just as the accelerator controls the flow of fuel, this expansion and contraction controls the quantity of refrigerant supplied to the evaporator coil to achieve the better cooling efficiency for the system and it allows precise control of the refrigerant flow to the evaporator coil, preventing the coil from becoming overcharged or overfed with the refrigerant.
