  • the two control valves are connected via a common connecting channel, which is also located in the valve block.
  • This known control device therefore has a complex structural design. The operability is not optimal for the following reasons.
  • Each control valve includes three switch positions. This results in a total of nine different switch positions of the two control valves so their control levers to each other. In practice this leads to that the operator must move the control lever of both control valves in the required manner.
