The Expansion Valve Coil is an electromagnetic component that actuates the expansion valve, regulating refrigerant flow in response to system demands. In heating and cooling systems, the coil ensures precise control over superheat and evaporator performance. This part is designed for compatibility with specific valve bodies, offering reliable operation under varying electrical conditions. When replacing an expansion valve coil, it is important to match voltage and resistance specifications to avoid system inefficiencies. A quality coil contributes to energy savings and consistent temperature regulation in your boiler or HVAC system.
