5.4 Valve variants
The valves are always rigidly mounted in a connection block. This block is directly integrated
in the hydraulic power unit. The hoses (pressure and return) are always connected to the
connection block. The units are equipped with either a 2POWER or a 4POWER connection
block.
The hoses and equipment are connected with the connecting block via plug couplings.
5.4.1 Control valve "Two fl ow mode" (2POWER)
This valve enables the connection of two double-acting hydraulic units. With this valve you
can operate two units at the same time and independently of each other.
You have two switching possibilities. The two switching levers can be used to pressurise or
depressurise the individual connections.
5.5.2 Control valve "Four fl ow mode" (4POWER)
This valve enables the connection of four double-acting hydraulic units. With this valve you
can operate four units at the same time and independently of each other.
ATTENTION!
When operating several rerailing units with one unit, ensure that the usable
volume of hydraulic fl uid in the reservoir is greater than the maximum possible oil
volume of all connected rerailing units. In the hydraulic fl uid tank, we differentiate
between the fi lling volume and the usable volume.
You have four switching possibilities. The four switching levers can be used to pressurise or
depressurise the individual connections.
