Intended use

The intended use of the Pressure control panel BM56-2U is the expansion of a gas from a gas source and the distribution of the gas with adjustable outlet pressure.

Pressure control panels of type BM56-2U are suitable for flammable gases, non-flammable gases, non-corrosive gases and for oxygen up to gas quality 6.0.

The permissible gas types and pressure ranges are each specified on the label (see "Identification / label").

Pressure control panels with type code "56" are based on a two-stage pressure reduction of the inlet pressure to the required outlet pressure. While two-stage pressure relief ensures an extremely constant outlet pressure throughout the entire inlet pressure range (from "full" gas cylinder to almost "empty" gas cylinder), with single-stage pressure reduction, the outlet pressure can vary within a certain range.

The 2U pressure control panels are two-sided pressure control panels with a switching mechanism (2U). The switching mechanism switches automatically from the side that is currently in operation to the reserve side when the gas supply situation requires it. The lever position of the switching mechanism indicates which side is the operational side and which the reserve side.

The pressure control panel is equipped with a process gas valve and an exhaust gas valve on each side.

The equipment versions of the Pressure control panels without electrical components may be used in an explosion hazard zone as they do not have separate ignition sources (ignition hazard assessment according to DIN EN ISO 80079-36).

Pressure control panels with electrical components that are suitable for use in an explosion hazard zone are marked on the label according to EU Directive 2014/34/EU.

To be able to use the Pressure control panels as intended, all persons working with it must comply with the specifications of the relevant user manual.

The area in which hazards can occur when used as intended is the area around the Pressure control panels. The danger zone changes depending on the system status and use.
