Technical description

The DUNGS GasMultiBloc integrates filter, regulator, valves and pressure switches in one compact fitting.

Dirt trap: microfilter

One regulator and two main valves: B01

One 1-stage valve and one 2-stage valve

One valve is fast opening, one valve is slow or fast opening

Solenoid valves up to 360 mbar (36 kPa) as per DIN EN 161 Class A Group 2

Sensitive setting of output pressure by proportional regulator as per DIN EN 88 Class A Group 2

High flow rates with low pressure drop

DC solenoid drive interference degree N

Main volume restrictor and partial volume restrictor at valve V2

Hydraulic opening delay

Flange connections with pipe threads as per ISO 7/1

Simple mounting, compact, light weight

Application

The modular system permits individual solutions in gas safety and regulator engineering. Suitable for gases of families 1, 2, 3 and other neutral gaseous media.

Specifications

Nominal diameter: Rp 1, 1 1/4, 1 1/2, 2 (flange with pipe threads as per ISO 7/1, DIN 2999)

Max. operating pressure: 360 mbar (36 kPa)

Output pressure ranges: 4 - 20 mbar (0.4 - 2 kPa)

Media: Gases of families 1, 2, 3 and other neutral gaseous media

Ambient temperature: -15 °C to +70 °C (Do not operate MB-ZR below 0°C in liquid gas systems)

Dirt trap: Sieve, microfilter, changing the filter is possible without removing the valve.

Pressure switch: GW 50 A5 (attached)

Pressure regulator: Pressure regulator compensated for residual pressure, leakproof seal when switched off by means of valve V1 as per DIN EN 88 Class A. Setpoint spring permanently installed (no spring exchange possible). A vent line above roof is not required. Internal pulse tap provided.
