Kromschroder Gas solenoid valve 88000140

This is a replacement solenoid coil for the Kromschroder VAD115R/NW-25B gas solenoid valve. It operates at 230 V AC and has an IP65 protection class. The coil is designed for use with valves having a pressure range of 2.5–25 mbar and an Rp internal thread. It is suitable for operating temperatures from -20 to 60 °C and incorporates high safety features.

When selecting a replacement coil for this type of valve, ensure the coil voltage matches the burner control output and that the coil is compatible with the valve body series and thread type. The coil must fit the specific valve model, so verify the valve's model and thread size (e.g., Rp internal thread) before ordering. Installation typically involves removing the old coil and securing the new one in place, ensuring proper electrical connection.

Common failure modes for such coils include burnout from overheating, short circuits, or mechanical damage to the winding. When a coil fails, the valve may not open, causing the burner to shut down or fail to ignite. Check the coil for continuity and visual damage, and verify the supply voltage is correct.
