Directional cartridge valves – These Bosch Rexroth hydraulic valves are elements that have been designed for a compact block design,. the power part is installed in a receiving hole of the manifold (according to ISO 7368) and closed with a control cover:

  • Bosch Rexroth Logic Elementslogic elements – directional function:  LC2A, LC, LFA, LFA..E..
  • logic elements – pressure function: LC..DB, LFA..DB, LFA..DB..E (pressure relief function), LC..DR and LFA..DB (pressure reducing function, rest position open), LC..DB and LFA..DR (pressure reducing function, rest position closed) and LC..DB, LFA..DZ (pressure sequence function).

Thank you, Joanna. Mark’s quote was from a technical discussion which answered many questions that I have been trying to get without success from other suppliers. Please thank Mark for his time and expertise; it was so refreshing to have a knowledgeable person rather than a sales assistant.
