Configurable, proportional mobile vales and LS technology

Mobile valves in sectional or plate design are used when, for example, several functions have to be implemented in parallel in a confined space, load-independent behavior of the control is required or numerous additional functions, e.g. safety functions such as shock suction valves or load holding valves/lowering brake valves, have to be integrated.

An example of a sounding vehicle for ground measurements is shown below.

The task is to lower and position the vehicle using four cylinders. Each cylinder has a stroke of 1.8 m and a bore diameter of 250 mm. In this case, the drive is provided by two fixed displacement pumps of 48l/min and 7l/min respectively.
