Kromschroder Gas solenoid valve VG8R05T6 85231010

The Kromschroder VG8R05T6 is a normally closed gas solenoid valve with a nominal diameter of 8 mm and a connection thread of Rp 1/4". It operates at a supply voltage of 230 V and can handle a maximum inlet pressure of 500 mbar. This valve is suitable for use with natural gas, LPG, air, and biogas, and is designed for fast response and high durability. It is manufactured in Germany.

When selecting a replacement gas solenoid valve of this type, verify the connection size (e.g., Rp 1/4") and the coil voltage (e.g., 230 V) to match the existing pipework and control system. Ensure the maximum inlet pressure rating meets or exceeds the system's operating pressure. The valve should be installed in the correct orientation, typically with the flow direction indicated on the body, and electrical connections must be made according to the wiring diagram.

Common failures of gas solenoid valves include coil burnout, which may cause the valve to fail open or closed, and leaking valve seats, leading to gas bypass. A damaged servo regulator or seized diaphragm can cause drifting outlet pressure. Symptoms on the equipment include burner ignition failure, unstable flame, or gas odor. Check the coil resistance and inspect the valve seat and diaphragm for wear or debris.
