Product Description

Technical description

 

Filter, valves, regulator and pressure switch are integrated in the DUNGS GasMultiBloc to form a compact fitting.

- Dirt trap:Microfilter

- One regulator and two valves

- Two valves (fast opening)

- Regulator (fast opening) or regulator (slow opening)

-Solenoid valves as per DIN EN 161 Class A Group 2 MBC-65 to 200 mbar (20 kPa) MBC-120 to 360 mbar (36 kPa)

- Sensitive setting of output pressure via servopressure regulator as per DIN EN 88 Class C Group 2

- Opening delay by means of damped pressure rise

-High flow values at low pressure difference

-DC voltage solenoid drive

- Main valve restrictor downstream of regulator - Flange connections with tube threads as per ISO 7/1

- Easy-to-mount, small dimensions, low weight

 

Application

The modular system provides individual solutions in gas safety and control systems. Suitable for gases of gas families 1, 2, 3 and other neutral gaseous media.
Approvals

 

EC type test approval as per EC Gas Appliance Directive:

MB-65/120-… CE-0085 AU 0377

EC type test approval as per EC Pressure Equipment Directive:

MB-65/120-… CE0036

Approvals in other important gas consuming countries.

 

Functional Description

Gas flow

1. Valves V1 and V2 are closed. Inlet pressure is applied to chamber A until valve V1 is seated. 2. The min. pressure switch is connected to Chamber A by a borehole. If the inlet pressure exceeds the reference value set on the pressure switch, it switches to the automatic gas burner control.

3. After a release signal from the automatic gas burner control, valves V1 and V2
open. The gas flow through chambers A, B, C and D of the GasMultiBloc is released.

Dirt trap device

Dirt trap device, fine-meshed filter (1) to protect the fitting.

Operating mode of valve V1 and valve V2

The plungers of valves V1 and V2 are connected to the valve plate units. On opening, the plungers pretension the closing springs. The valves open completely without limitation.

Closing function

When the power supply of solenoid coils of V1 and V2 is interrupted, the valves are closed within < 1s by means of pressure springs.

Operating mode of servopressure regulator

The servopressure regulator equalises the pressure fluctuations in the

power supply. The output pressure is set at the reference value adjustment device (14). The servopressure regulator controls the
pressure regulator (5) via nozzle (7). The "slow opening" function is enabled by a damped pressure increase. The opening time of
MBC-120 cannot be set. With MBC-120, the opening behaviour can be adjusted at high operating pressure values.

Start flow adjustment

The adjustment screw (15) for the start flow restrictor (10) is closed (factory setting). The start flow can be set by
opening the restrictor up to approx. 80 % of the main flow.

Main flow adjustment

The adjustment screw (13) for the main flow restrictor (9) is completely open (factory setting). The servopressure regulator Sectional view MBC-65-DLE-S20 Pressure taps 1. Microfilter 2. Inlet P1 3.

Electrical connection 18 Setting of opening time (only MBC-120) keeps the output pressure upstream of the main flow restrictor constant. The burner pressure is determined when the output pressure and the main flow restrictor (9) are adjusted.

Gas pressure switch

The gas pressure switch
monitors the gas pressure on the inlet side; the pressure switch is preset.
