Kromschroder Solenoid gas valve VG8R05T6L 85231012

Kromschroder VG8R05T6L is a normally closed solenoid gas valve with fast response, designed for automatic gas supply control in small systems and pilot lines. It has a DN 8 (Rp 1/4") connection, operates at up to 500 mbar, and is rated for 230 V AC. This valve is suitable for natural gas, LPG, and air, and meets safety class A according to EN 161. It is categorized under valve coils and identified by SKU 85231012.

When selecting a solenoid gas valve of this type, confirm the coil voltage (e.g., 230 V AC or 24 V AC/DC) and the connection size (typically Rp 1/4" to 2" or flanged). For multiblock assemblies, verify the mounting pattern and whether the replacement includes a filter and regulator. The valve is installed downstream of the gas filter and upstream of the burner, and must match the burner control and gas pressure switch requirements.

Common failures include coil burnout, leaking seat, drifting outlet pressure, or a seized servo regulator. Symptoms may include the burner failing to ignite, gas flow continuing when it should stop, or unstable flame. Check the coil continuity, valve seat sealing, and outlet pressure against specifications.
