Kromschroder Gas solenoid valve VG 15/10R01T6 85234010

Kromschroder VG 15/10R01T6 is a normally closed gas solenoid valve with SKU 85234010. It is designed for automatic control and shut-off of gas and air supply in heating systems, gas burners, boilers, and process equipment. The valve has a connection diameter of DN 15/10, internal thread Rp, maximum pressure up to 100 mbar, and supply voltage 220/240 V AC, 50/60 Hz. It weighs approximately 0.5 kg and is certified to Class A according to EN 161.

When selecting a replacement valve of this type, confirm the connection size (e.g., Rp 1/2" to 2"), coil voltage (e.g., 230 V or 24 V AC/DC), and function (single or double solenoid, slow-opening, etc.). The valve must match the gas train configuration, typically installed after a gas filter and before the burner nozzle. Ensure the valve's pressure rating and media compatibility (natural gas, LPG, air) suit the system. The coil is often replaceable separately from the valve body, so verify the exact series designation and coil voltage before ordering.

Typical failures include a leaking seat, drifting outlet pressure, or a seized servo regulator. If the coil burns out, the valve may fail to open, preventing gas flow. A faulty valve can cause the burner to shut down or fail to ignite, often indicated by a loss of flame signal or safety trip. Check the coil resistance and valve operation with a multimeter, and inspect for debris or wear on the seat.
