Compact Directional Valves - Non-compensated and Post-compensated - Intermediate elements ED Series

TI-M412

Description

The adaptor elements TI-M412 -__ are employed to connect an ED directional valve assembly to a main control valve Rexroth M4-12.

These elements basically consist of body made of Yellow Zinc plated (Cr+3) steel which incorporates the following items:

  • a check valve on the P - P1 line.
  • a shuttle valve on the LS lines.
  • a relief valve on the un the LS line which controls the maximum pressure output from the pump.
  • a pressure compensated orifice which drains to tank the LS pressure by unloading a small regulated flow.
