Bosch Rexroth WE Directional Spool Valve – Direct Operated, Solenoid Actuation – WE 73 – A12

Solenoid Operated Directional Control Valves


Bosch Rexroth WE 73- A12 direct operated directional spool valves have solenoid actuation and smooth switching behaviour. They control the start, stop and direction of flow. The structural design of the control spools and solenoids means that switching shocks when activating and deactivating the valves are significantly reduced. Directional spool valves connect or isolate the connections by moving a control spool in a housing bore.
The valve has a maximum operating pressure of 350 bar and a maximum flow of 60 l/min, with a smooth switching behaviour.
Other features of the WE 73- A12 spool valve include:

  • 4/2- or 4/3-directional version;
  • ISO 4401 porting pattern;
  • Wet-pin DC solenoids with detachable coil;
  • The coil can be changed without having to open the pressure-tight chamber.
