Kromschroder Solenoid gas valve VG8R18T6 85232010

Kromschroder VG8R18T6 is a normally closed solenoid gas valve with fast response, designed for gas shut-off in pilot lines and small systems. It operates at 230 V AC and has a maximum working pressure of 500 mbar. The valve has a DN 8 (Rp 1/4") connection and is safety class A according to EN 161. It is suitable for natural gas, liquefied gas, and air.

When selecting a replacement solenoid valve coil of this type, verify the voltage (typically 230 V or 24 V AC/DC), power rating, electrical connection type (e.g., plug-in spade terminals or flying leads), and physical dimensions that match the valve body's yoke. Ensure the coil fits the valve stem diameter and mounting bracket of the specific VG series valve. Check the marking on the old part and confirm the new coil is compatible with the valve body. Always isolate gas and electrical power before replacement, and ensure the coil is fully seated with the locking mechanism engaged.

Common failures of solenoid valve coils include open-circuit winding from thermal stress or shorted turns from moisture ingress. Symptoms may include the valve failing to open or close, slow response, or the coil burning out. Check the coil for continuity and insulation resistance, and inspect the gasket or o-ring for damage that could allow dust or moisture entry.
