GasMultiBlocCombined regulator andsafety shut-off valvesSingle-stage function<strong>MB</strong>-D(LE) <strong>415</strong>-<strong>420</strong> <strong>B01</strong>7.02Printed in Germany • Rösler Druck • Edition 08.00 • Nr. 225 7581 … 6Technical descriptionThe DUNGS GasMultiBloc integrates filter,regulator, valves and pressure switchesin one <strong>com</strong>pact fitting. Various designsare possible by the modular system:- Dirt trap: microfilter- One regulator and two valves: <strong>B01</strong>- Two valves are fast opening- One valve is fast opening and one valveis slow opening- Solenoid valves up to 360 mbar as perDIN EN 161 Class A Group 2- Sensitive setting of output pressure byproportional regulator as per DIN EN88 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 threadsas per ISO 7/1- Simple mounting, <strong>com</strong>pact, light-weightThe modular system permits individualsolutions by using external ignition gas tapin connection with separately controlledvalves, by adding a valve proving system,mini/maxi pressure switches, pressurelimiters, limit switch at valve V2.ApplicationThe modular system permits individualsolutions in gas safety and regulator engineering.Suitable for gases of families 1, 2,3 and other neutral gaseous media.ApprovalsEU type test approval as per EU GasAppliance Directive.<strong>MB</strong>-D(LE) <strong>415</strong> <strong>B01</strong> CE-0085 AR 0233<strong>MB</strong>-D(LE) <strong>420</strong> <strong>B01</strong> CE-0085 AR 0233Approvals in other important gas-consumingcountries.
