4/3 Proportional valve elements

B8_80 (EDB-P)

Compact direct-operated proportional solenoid valves

Marginal Column

Valve elements B8080… are compact direct operated proportional solenoid valves which control the start, stop, direction and the quantity of the oil flow. They consist of a stackable housing with a control spool, one or two solenoids, and one or two return springs. Energized by an electronic feed regulator, each solenoid displaces the control spool from its neutralcentral position “0” proportionally to the current received. In open loop mode, a regulated oil flow P to A , or P to B, is achieved.

Features

  • 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

Spool variants:

B2: 4/3 operated both sides a and b; P -- T closed in neutral

E2: 4/3 operated both sides a and b; A and B to T in neutral
