Control blocks


Control blocks are the controlling centers for drive and working hydraulics in mobile machines.

The range of products includes all hydraulic function elements necessary for this purpose as well as the corresponding designs (mono- and plate blocks, plug-in and externally mounted elements). It is complemented by integrated electronic sensors, controls and control elements.

 

Adapted to the individual machine concepts there are various control systems available:

- Open Center (OC)

- Positive Control (PC)

- Load-independent flow sharing (LUDV)

- Load Sensing (LS)
