Serpentina della valvola di espansione De Dietrich 767850800

The expansion valve coil is an electromagnetic component that controls the opening of the expansion valve in response to system demands. It plays a key role in regulating refrigerant flow for optimal performance in heating and cooling cycles. If the coil fails, the valve may not operate correctly, affecting efficiency. Replacing a defective expansion valve coil restores proper function and helps maintain system balance.
