4/3 Directional valve elements, with PO check valves

B8_45... (EDBY-VR)

Compact direct-operated solenoid valves

Marginal Column

Directional valve elements B8_45… are compact direct-operated solenoid valves which control the start, stop and direction of the oil flow. These elements consist of a stackable housing with a control spool, two solenoids, and two return springs. The upper part of the housing is extended in order to provide space for the cavities where two PO check valves are fitted. They consist of two calibrated balls with return springs that allow upstream flow, but lock on the respective seats and prevent the return flow. Return flow is possible when they are opened by the pilot piston if enough pilot pressure is present in the opposite line.


  • Valve elements with 4 ways and 3 positions
  • Control spools directly operated by screwed-in solenoids with extractable coils
  • In the de-energized condition, the control spool is held in the central position by return springs
  • Wet pin tubes for DC coils, with push rod for mechanical override; burnish surface treatment
