EOGB MBZRDLE 412 B07 S22 Gas Valve with Pressure Switch

The MBZRDLE 412 B07 S22 is a gas valve with an integrated pressure switch, manufactured under the EOGB Dungs range. It controls the supply of gas to the burner on boiler appliances and provides pressure proving as part of the combustion control sequence. It is supplied as a complete valve assembly for use in the boiler types it is listed against.

• The burner fails to light or the appliance locks out repeatedly during the ignition sequence.
• The pressure switch does not prove, giving a fan or air pressure fault at the controls.
• Gas is smelt at the valve body or at the valve connections.
• Unstable or weak flame, with the burner cutting out shortly after ignition.
• The valve fails to shut off fully when the appliance is at rest.

• Check the appliance data plate and existing valve label to confirm the MBZRDLE 412 B07 S22 reference matches exactly.
• Confirm the valve is being fitted to an EOGB Dungs boiler application.
• Verify the gas type and supply pressure against the appliance documentation before fitting.
• Gas-carrying components must be fitted and commissioned by a competent, registered gas engineer.
