4-way valve coil De Dietrich 770192100

The 4-way valve coil is an electromagnetic component that actuates the reversing valve in heat pump and some boiler systems. This coil controls the direction of refrigerant flow, allowing the system to switch between heating and cooling modes. As a critical spare part for burner and heating equipment, it is commonly replaced when the valve fails to shift properly, causing temperature inconsistencies. The coil is designed to be a direct replacement for specific models, ensuring compatibility with your existing valve body. Regular maintenance of this part helps maintain efficient operation of your heating and cooling components, and it is a common item in service sets for gas burner repairs.
