GasMultiBloc Combined regulator and safety shut-off valves MB-ZRD(E) 05 - B0 7. Edition 08.5 r. 76 5 Technical description The DUGS GasMultiBloc integrates filter, regulator, valves and pressure switches in one comct fitting. - Dirt trap: Fine-mesh sieve - One regulator and two main valves: B0 - 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 60 mbar (6 ka) as per DI E 6 Class A Group - Sensitive setting of output pressure by proportional regulator as per DI E 88 Class A Group - High flow rates with low pressure drop - DC solenoid drive interference degree - Main volume restrictor and rtial volume restrictor at valve V - Hydraulic opening delay - Flange connections with pipe threads as per ISO 7/ - Simple mounting, comct, light-weight The modular system permits individual solutions by using external ignition gas tap in connection with serately controlled valves, by adding a valve proving system, mini/maxi pressure switches, pressure limiters, limit switch and closing stroke limiter at valve V, regulator blocking for liquid gas applications. Application The modular system permits individual solutions in gas safety and regulator engineering. Suitable for gases of families,, and other neutral gaseous media. Approvals EC type test approval as per EC Gas Appliance Directive: MB-ZR...05- B0 CE-0085 A 56 EC type test approval as per EC ressure Equipment Directive: MB-ZR...05- B0 CE006 Approvals in other important gas consuming countries.
