Magnetventilspule 21s4 De Dietrich 7652680

The solenoid valve coil 21s4 is an electrical actuator for solenoid valves used in gas and liquid control circuits. It generates a magnetic field to open or close the valve, enabling automated flow regulation in boiler and burner systems. This coil is commonly used in safety shut-off or control applications. When the original coil fails, replacing it with this 21s4 model restores valve functionality. Its standardized design ensures compatibility with many valve bodies, making it a practical spare for heating maintenance.
