Kromschroder Solenoid coil VGP20-25...W/B 04005182

Kromschroder Solenoid coil VGP20-25...W/B 04005182 is a replaceable electromagnetic actuator for gas valves of the VGP20-25 series. It mounts onto the valve body and, when energized with the correct voltage, lifts the valve seat to admit gas to the burner. On loss of power, a spring returns the valve to the closed position, providing safety shut-off. This coil is designed to fit Kromschroder VGP20-25 valves.

When selecting a replacement coil for a gas valve of this class, verify the coil voltage (typically 230 V or 24 V AC/DC) and the mechanical interface with the valve body. The series designation indicates valve body size and function; the coil must match both the electrical specification of the burner control and the physical mounting of the existing valve. Check the voltage and series marking on the old coil before ordering. The coil can often be replaced without removing the valve body, provided the gas supply is isolated and system pressure released.

Typical failure modes include open-circuit windings from thermal stress or voltage surges, and intermittent operation due to partial shorting. When the coil fails, the valve may not open or may close unexpectedly, causing burner shutdown or failure to ignite. Check the coil for continuity and insulation resistance, and verify the voltage supply to the coil.
