Technical Description
The DUNGS multiple actuator MBC…VEF offers filter, valves and servo pressure regulator in one compact unit:
- Dirt trap: microfilter
- 2 solenoid valves up to 360 mbar (36 kPa) as per DIN EN 161 class A group 2
- Servo pressure regulator as per DIN EN 88 class A group 2; EN 12067-1
- Fine setting of gas and air pressure ratio
- Flange connections with pipe threads as per ISO 7/1 or NPT
- Easy to install
- Low weight

As this system has a modular design, we can offer individual solutions with valve inspection system, pressure switches mini/ maxi and pressure limiters.High flow values at low pressure difference.

Application
The servo pressure regulator permits optimum mixture formation in forced air burners and premix burners; this applies to modulating and multi-stage variable operating modes.
Suitable for gases of gas families 1, 2, 3 and other neutral gaseous media.

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