In combination with a pressure controller, it limits the maxithe variable pump. The variable pump only supplies as much
hydraulic fluid as is required by the consumers.
In combination with a remote controlled pressure controller
DG, LS pressure limitation takes place via a separate pressure relief valve. More information can be found in data
sheets 92701, 92703 and 92705.
