Double solenoid valve
Combined pressure regulator and safety valves
Gas-air-ratio-control

MBC-...-VEF
DN 65 - DN 100

Technical Description
The DUNGS multiple actuator MBC-...-VEF integrates 2 valves and 1 gas-air ratio regulator in one compact unit:
- Solenoid valves up to 500 mbar (50 kPa) as per DIN EN 161 Class A Group 2
- Fine setting of gas and air pressure ratio
- Servo pressure regulator as per DIN EN 88 class A group 2; EN 12067-1
- Internal stepping lines for optimised outlet pressure stability, external as an option.
- Flange connection as per ISO 7005
- Easy to install

As this system has a modular design, we can offer individual solutions with valve testing system, mini/maxi pressure switch and pressure limiter. Despite the compact design, high flow rates can be achieved at low pressure difference.

Application
The gas-air ratio regulator permits optimal mixture formation in forced air burners and premix burners. This applies to modulating and two-stage variable operating modes.
Suitable for gases belonging to gas families 1, 2, 3 and other inert gaseous media.

Approvals
EC type testing certificate as per:
• EC-Gas Appliances Regulation
• EC-Pressure Equipment Directive
Approvals in other important gas-consuming countries.
