Dungs GasMultiBloc MBC

    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.

Dungs GasMultiBloc MB-DLE - Single Stage Operation

    This GasMultiBloc MB-DLE integrates a filter, pressure regulator, two class A valves, a bypass valve (B07) and pressure switches in one compact fitting.
    The modular system permits individual solutions by using external ignition gas tap in connection with separately controlled valves, by adding a valve proving system, min/max pressure switches, pressure limiters, partial volume setting by closing stroke limiter at valve V2 and regulator blocking for liquid gas applications.
    Maximum operating pressure is 360 mbar (200 mbar for MB-DLE 403), ambient temperature -15÷70ºC (only above 0 for LPG), degree of protection IP 54.
    The two valves are controlled in common or separated, depending on the model; both are fast closing. V1 is with fast-opening and V2 with slow-opening
    Main volume restrictor at valve V2.
    MB-DLE B07 series has an additional bypass valve with fast opening.
    Different pressure switch types mountable: GW A5, GW A2, NB A2, UB A2. Standard equipped with GW 150 A5.
    The pressure regulator has a setpoint spring permanently installed, no exchange possible. A vent line above roof is not required.
    MB-DLE 403-412 models have a fine mesh sieve, replacement only possible by dismounting the fitting. MB-DLE 415 and 420 have a pre-mount filter that can be changed without removing the valve.
    Simple mounting, compact, light-weight.
    Suitable for gases of families 1, 2, 3 and other neutral gaseous media.

Dungs GasMultiBloc MB-ZRDLE (MB-ZR) - Two Stage Operation

    This MB GasMultiBloc MB-ZRDLE integrates a filter, pressure regulator, two class A valves, a bypass valve (B07) and pressure switches in one compact fitting.
    The modular system permits individual solutions by using external ignition gas tap in connection with separately controlled valves, by adding a valve proving system, min/max pressure switches, pressure limiters, limit switch and closing stroke limiter at valve V2, regulator blocking for liquid gas applications.
    Maximum operating pressure is 360 mbar, ambient temperature -15÷70ºC (only above 0 for LPG), degree of protection IP 54.
    The two valves are controlled in common or separated, depending on the model; both are fast closing. V1 is with fast-opening and V2 with fast or slow-opening
    Main volume restrictor and partial volume restrictor at valve V2.
    MB-ZRDLE B07 series has an additional bypass valve with one stage and fast opening.
    Different pressure switch types mountable: GW A5, NB A2, UB A2. Standard equipped with GW 150 A5.
    The pressure regulator has a setpoint spring permanently installed, no exchange possible. A vent line above roof is not required.
    MB-ZRDLE 405-412 models have a fine mesh sieve, replacement only possible by dismounting the fitting. MB-ZRDLE 415 and 420 have a pre-mount filter that can be changed without removing the valve.
    Simple mounting, compact, light-weight.
    Suitable for gases of families 1, 2, 3 and other neutral gaseous media.

Dungs GasMultiBloc MB-VEF

    This GasMultiBloc MB-VEF integrates a filter, gas/air ratio controls, two class A valves and a pressure switch.
    The gas/air ratio control ensures optimal mixture formation in forced air burners and pre-mix burners; this applies to floating and two-step floating operations.
    Maximum operating pressure is 360 mbar, output pressure range 0.5÷100 mbar, ambient temperature -15÷70ºC.
    Ratio V = pburner/pblower, air 0.75:1 up to 3:1.
    Zero point adjustment N.
    Different pressure switch types mountable: GW A5, GW A2, NB A2, UB A2. Standard equipped with GW 150 A5.
    External pulse lines, pulse flange.
    The modular kit ensures individual solutions comprising valve proving system, min/max pressure switches and pressure limiters.
    Suitable for gases of families 1, 2, 3 and other neutral gaseous media.
