GasMultiBloc® Combined regulator and safety shut-off valves Single-stage function
MB-D(LE) 403 B01

Technical description The DUNGS GasMultiBloc® integrates filter, regulator, valves and pressure switches in one compact fitting.
- Dirt trap: microfilter
- One regulator and two main valves: B01
- Two valves are fast opening
- One valve is fast opening, one valve is slow opening
- Solenoid valves up to 200 mbar (20 kPa) as per DIN EN 161 Class A Group 2
- Sensitive setting of output pressure by proportional regulator as per DIN EN 88 Class A Group 2
- High flow rates with low pressure drop
- DC solenoid drive interference degree N
- Main volume restrictor at valve V2
- Hydraulic opening delay
- Flange connections with pipe threads as per ISO 7/1
- Simple mounting, compact, lightweight

The modular system permits individual solutions by using external ignition gas tap in connection with separately controlled valves, by adding a valve proving system, mini/maxi pressure switches, pressure limiters, partial volume setting by closing stroke limiter at valve V2 and regulator blocking for liquid gas applications.

Application
The modular system permits individual solutions in gas safety and regulator engineering. Suitable for gases of families 1, 2, 3 and other neutral gaseous media.

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