Approvals in other important gas consuming countries

 

Functional description

Gas flow

1.If the valves V1 and V2 are closed, chamber a is under input pressure up to the double seat of
valveV1.

2.A hole in the filter housing of MB 407/412 connects min. pressure switch with chamber a. If the input pressure applied
to the pressure switch exceeds the incoming reference value, it switches through to the automatic burner control.

3.After release by the automatic burner control, valves V1 and V2 open. The gas flow through chambers a, b and c of the MultiBloc is then released.

Operating method of valve-regulator combination on valve V1

Operating method of valve-regula- tor combination on valve V1 A regulator compensated for residual pressure is integrated in valveV1 (pressure regulatingpart). Anchor V1 is not connected with the valve plate unit. When it opens, the anchor pretensions the pressure spring and releases the valve plate unit. When thevalve closes, the anchor acts directly on the valve plate unit. Valves V1 and V2 are released at the same time. In closed position valve V3 blocks the pressure chamber under working diaphragm M against input pressure pe in chamber a. The pressure under working diaphragm M is defined by a variable flow crosssection D.The comparison diaphragms for burner pressure pBr and blower pressure pL are interconnected via a rod. Moving the bearing point sets the ratioV. Zero point correction Nactson this rod. The ambient pressure pamb or the firing chamber pressure pF must be applied to the opposite side of the comparison diaphragms. Firing chamber pressure has a reducing effect on the burner pressure at a ratio ofV > 1. Changes resulting from the force equilibrium lead to a modification of the flow cross-section D downstream of valve V4. Pressure under the work- ing diaphragm is re-adjusted and the valve plate unit V1 changes the free cross section.

Operating method of valve V2

The anchor of valve V2 is connected with the valve plate unit.When it opens, the anchor pretensions the pressure spring.Valve V2 opens completely and without delay. Valve V4 is activated by valve V2. In closed position, valve V4 blocks the chambe runder the working diaphragm M from the burner pressure.

 

Closing function

When the supply voltage of the main valve solenoid coils is interrupted, the valves are closed within < 1 s by
the compression springs.
