Expansionsventil-Wärmetauscher 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.
