USE OF MODULAR DIRECTIONAL VALVES IN MOBILE HYDRAULICS

Whenever precise work and the sensitive control of complex movement sequences are among the core tasks of a mobile work machine, then the stable and controlled control of the hydraulic oil volume flow becomes the focus of attention. From the more than 30 meter long work platform to the drive in the open circuit, from drilling equipment to forestry machines to concrete placing booms: Many applications and work processes place the highest demands on valve technology in terms of precision, sensitivity, load independence and safety in order to be able to efficiently manage the required tasks.

Feature and Benefits

With the ED modular system, Bosch Rexroth Oil Control SpA provides a tried-and-tested family of valves that meets all of these requirements with maximum reliability and covers a very wide range of machine types. This means that a large number of applications can benefit from the high quality and benefit from the extensive field experience of the ED valve series.

The load-sensing technology with an optimally designed section pressure compensator enables the operator to proportionally control each individual consumer with the required precision - regardless of the load and position of the machine. A high level of operating comfort and thus high productivity are the result Hand in hand.

The well thought-out, modular design of the ED kit enables the machine manufacturer to configure the ideal control block for his application. By selecting the valve sections (sections/bankable) appropriately, he can control up to 10 functions with one ED block The flexibility here is great: Among other things, the options for selecting the nominal slide valve size, setting the volume flow to the exact liter or precise pressure limitation of the LS signal (fixed or electro-proportionally adjustable) enable an individual and optimal design for each machine function , hydraulic and electro-hydraulic.
With features such as the interruption of the LS signal or the redundant switch-off of the pump volume flow, Rexroth supports manufacturers in the implementation of functional safety specifications.

Further advantages of the consistent modularity are simplified commissioning and user-friendly service, since all assemblies and individual parts can be replaced without disassembling the block.
