Kromschroder Solenoid gas valve VG10R01T5 85233012

The Kromschroder VG10R01T5 (SKU 85233012) is a solenoid gas valve with a brass body and NBR seals, designed for automatic gas shut-off in gas burner and heating systems. It operates at 220–240 V AC, 50/60 Hz, with a pressure range of 0–100 mbar and a DN 10 connection via RP internal thread. The valve meets EN 161 safety standards with Class A certification, has IP54 protection, and operates in temperatures from -20 to 60 °C. It features a replaceable coil and is suitable for natural gas, town gas, LPG, and air.

Parts of this type are selected by operating voltage, which must match the existing coil's rating (commonly 230 V AC or 24 V AC/DC). The coil must also be mechanically compatible with the valve body, as mounting patterns and plunger strokes differ between valve series. Before ordering, verify the voltage marking on the existing coil and ensure the replacement coil is designed for the specific valve series.

Items of this kind typically fail due to a charred winding or an open circuit in the coil, which prevents the valve from opening and causes a lockout on the burner control. Check the coil with a multimeter for continuity and inspect for visible signs of burnout. If the coil is replaced and the valve still does not open, inspect the valve seat and servo regulator for debris or sticking.
