What it is
The MBDLE 420 B01 S50 is a gas valve supplied with a pressure switch, manufactured by EOGB and listed under the EOGB - Dungs model range. It controls the flow of gas to the burner on boiler appliances within that range. The assembly combines the gas valve body with a pressure switch for the same application.
Signs this part needs replacing
- The burner fails to light, or lights intermittently, when there is a call for heat
- The boiler locks out shortly after start-up or part way through a cycle
- The flame is weak or unstable at the burner
- No gas reaches the burner despite the appliance calling for heat
- Pressure switch faults trigger repeated lockouts
Before you order
- Confirm the part number on the existing valve matches MBDLE 420 B01 S50
- Check that the appliance is in the EOGB - Dungs range
- Confirm whether the existing installation uses a pressure switch, as this valve is supplied with one
- Gas work must be carried out by a competent, registered engineer
