GasMultiBloc MBC Dungs

Gas Multi Bloc MBC Dungs
  • This MB GasMultiBloc MBC integrates a filter, servo pressure regulator, two class A valves and a pressure switch in one compact unit. They represent the newest and most modern series of Dungs gas blocks.
  • The modular system provides individual solutions in gas safety and control systems
  • MBC-65 and MBC-120 models are used for one-stage mode burners. In MBC-...-SE models the servo pressure regulator permits optimal mixture formation in forced air burners and premix burners in conjunction with mechanical or electronic integrated gas-air regulation units; it applies to modulating and multi-stage operating mode.
  • The two valves are fast opening and fast closing, the dirt trap is different according to the type (see table below).
  • Different pressure switch types mountable: GW A5, GW A2, NB A2, UB A2. Standard equipped with GW 150 A5.
  • Reference value spring is installed permanently, no spring replacement possible for MBC-65 and MBC-120. Bigger models have different type of springs for different pressure ranges. They can also be equipped with versions for zero pressure and gas-air ratio control .
  • Optional external pulse for MBC-1900 - 5000.
  • High flow valves at low pressure difference.
  • Simple mounting, compact, light-weight.
  • MBC-...-SE can also be used to replace the old double solenoid gas valves DMV-SE and MBC-...-VEF replaces DMV-VEF.
  • Suitable for gases of families 1, 2, 3 and other neutral gaseous media.
