Double solenoid valve
Combined pressure regulator and safety valves Servo pressure regulator

MBC-...-SE
DN 65 - DN 100

Technical Description
The DUNGS multiple actuator MBC-...-SE integrates valves and servo pressure 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 outlet pressure
- Servo pressure regulator unit as per DIN EN 88 Class A Group 2
- Setpoint spring replaced
- Outlet pressure: 4 - 300 mbar (0.4 - 30 kPa)
- Internal stepping lines for optimised outlet pressure stability, external as an option.
- Flange connection as per EN 1097-1
- Easy to install
- Low weight

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 servo pressure regulator permits optimal mixture formation in forced air burners and premix burners in combination with mechanical or electronic gas/air regulation units. This applies to modulating and multistage 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.
