The Dungs MBE and MBE-S MultiBloc Generation E platform is the newest development in compact gas train design for UK industrial and commercial combustion systems. The modular architecture combines a ValveBody, dual or single ValveDrive modules, and optional PressureSensor functionality to provide precise, stable, and safe fuel delivery within a compact housing.

This modern assembly supersedes various legacy Dungs DMV and older MultiBloc valves. Many of these earlier devices are now discontinued or being phased out. The MBE series therefore serves as the recommended replacement across the UK market for manufacturers, consultants, and service engineers.

Comtherm hosts the only UK digital configurator for the MBE range. It automatically selects the correct ValveBody size, actuation modules, and pressure sensing arrangements. This eliminates ordering errors, improves system design efficiency, and supports consistent specification across projects.

The range is suited to industrial burners, thermal processing lines, CHP engines, powder coating plants, furnaces, ovens, and a wide range of process heating environments. Its integrated design reduces installation effort, shortens commissioning time, and maintains safety through EN 161 Class A shutoff performance.

The MBE and MBE-S assemblies introduce enhanced performance parameters intended to support modern industrial burner systems and satisfy UK compliance requirements. They incorporate dual or single EN 161 Class A shut-off valves, optional electronic regulation, and stepper-driven actuation for smooth, precise control.

The stepper motor design allows accurate valve travel, improved modulation control, and extended service life. Pressure sensing, when combined with the MBE-VR configuration, integrates directly with burner management system safety chains to ensure correct shutdown behaviour under overpressure or pressure-loss conditions.

The MBE and MBE-S assemblies are certified for the following fuel gases:

• Manufactured Gas (Family 1)
• Natural Gas NG (Family 2)
• LP Gases in vapour phase (Family 3)
• Dry hydrogen up to 100 percent
• Biogas up to 1.0 percent H₂S
• Digester gas

Certification includes CE, UKCA, EN 161, EN 13611, EN 437:2018, and compliance with the UK Gas Appliance and Pressure Equipment regulations.

The MBE range is widely used across UK industrial burners, process heating lines, CHP systems, furnaces, food processing, drying systems, and hydrogen demonstration rigs. With many DMV valves now discontinued, the MBE serves as the recommended modern replacement.

Typical UK applications include:

• Industrial burners and boilers
• Paint curing and powder coating equipment
• Food ovens and thermal processing systems
• CHP gas engines
• Kilns and furnaces
• Biogas and digester gas systems
• Hydrogen-ready combustion equipment

Comtherm automatically redirects searches for discontinued valves to the correct MBE series equivalents.

Are Dungs DMV valves still available?
Many DMV variants are now discontinued or being phased out. The updated MBE range is the recommended successor for UK industrial combustion systems.

What is the difference between MBE and MBE-S?
Both share the same design principles, although the MBE-S uses a single valve stage while retaining compatibility with pressure sensing and regulation options.

Is the MBE range certified for hydrogen?
Yes. The full platform is certified for dry hydrogen up to 100 percent.

What industries use these valves?
They are deployed in industrial heating, food processing, thermal coating lines, CHP systems, chemical processing, and hydrogen-ready installations.

How do I select the correct configuration?
Comtherm provides a tailored configurator that determines the correct ValveBody, ValveDrive, and sensor combination.
