P&ID BM55-2U

The intended use of the Pressure control panel BM55-2U is the expansion of a gas from a gas
source and the distribution of the gas with adjustable outlet pressure.

The 2U pressure control panels are two-sided pressure control panels with a switching mechan-
ism (2U). The switching mechanism switches automatically from the side that is currently in op-
eration 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.

You select which side of the pressure control panel is to be used by operating the switching
mechanism:

– Lever up: the pressure regulator on the left is in operation

– Lever down: the pressure regulator on the right is in operation
