GasMultiBloc Combined regulator and safety shut-off valves MB-D(LE) 05 - B0 7. Edition 0.8 r. 76 5 Technical description The DUGS GasMultiBloc integrates filter, regulator, valves and pressure switches in one compact fitting. - Dirt trap: Fine mesh-sieve - One regulator and two valves: B0 - Two valves are fast opening - One valve is fast opening and one valve is slow opening - Solenoid valves up to 60 mbar (6 kpa) 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 at valve V - Hydraulic opening delay - Flange connections with pipe threads as per ISO 7/ - 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, limit switch V. 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 testing certificate as per: EC-Gas Appliances Regulation EC-Pressure Equipment Directive Approvals in other important gas consuming countries.

Only suitable for gaseous liquid gas, liquid hydrocarbons destroy sealing materials.) Fine mesh-sieve, replacement only possible by dismounting the fitting. Types GW A5, GW A, B A, ÜB A mountable as per DI E. For further information, refer to Datasheet GW A o. 5 8 and Datasheet GW A5 o. 5 90. Pressure regulator compensated for residual pressure, leakproof seal when switched off by means of valve V as per DI E 88 Class A. Setpoint spring permanently installed (no spring exchange possible). A vent line above roof is not required. Internal pulse tap provided.
