GasMultiBloc® Combined regulator and safety shut-off valves Single-stage function Integrated bypass valve
MB-D(LE) 407 - 412 B07
Technical description
The DUNGS GasMultiBloc® integrates fi lter, regulator, valves and pressure switches in one compact fitting.
- Dirt trap unit: Fine-mesh sieve
- One regulator, two main valves and one bypass valve: B07
- Two valves are fast opening, one valve is slow opening
- Solenoid valves up to 360 mbar (36 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 fl ow rates with low pressure drop
- DC solenoid drive interference degree N
- Main volume restrictor at valve V2, bypass restrictor at valve V3
- 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 an internal bypass valve in connection with separately controlled valves, by adding a valve proving system, mini/maxi pressure switches, pressure limiters, limit switches at valve V2.
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.
