GasMultiBloc®
Combined regulator and safety shut-off valves Two-stage function
MB-ZRD(LE) 415 - 420 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
- One one-stage valve and one two-stage valve
- One valve is fast opening, one valve is slow or fast 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 flow rates with low pressure drop
- DC solenoid drive interference degree N
- Main volume restrictor and partial volume restrictor at valve V2
- Hydraulic opening delay
- Flange connections with pipe threads as per ISO 7/1
- Simple mounting, compact, light-weight
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, limit switch 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.
Approvals
EU type testing certificate as per:
• EU-Gas Appliances Regulation
• EU-Pressure Equipment Directive
Approvals in other important gas consuming countries.
