Control valve
Opening and closing of the movable clamping ring, there are four
different positions:
-
To the left side: movable clamping ring closes.
-
In the middle (usual position): the pressure which is currently
achieved is kept (also by means of the built-in hydraulic
accumulator)
-
Slightly to the right side (position depressurized): a possibly
existing pressure is released without opening the machine.
Due to the hydraulic accumulator, it takes about 10 s until the
pressure is completely released
-
To the right side: movable clamping ring opens.
