They control the start, stop and direction of a flow. The directional valves basically consist of the housing (1), one or two electronic solenoids (2), the control spool (3), and one or two return springs (4). In the de-energized condition, the control spool (3) is held in the central position or in the initial position by the return springs (4) (except for version "O"). The control spool (3) is actuated by wet-pin electronic solenoids (2). For perfect functioning, the hydraulic system must be bled properly . The force of electronic solenoid (2) acts via the plunger (5) on the control spool (3) and pushes the latter from its rest position to the required end position. This enables the necessary direction of flow from P to A and B to T or P to B and A to T. When the electronic solenoid (2) is de-excitated, the return spring (4) pushes the control spool (3) back to its rest position. An optional manual override (6) allows the control spool (3) to be moved without solenoid energization. Without spring return "O" (only possible with symbols A, C and D) This version is a directional valve with two spool positions and two electronic solenoids without detent. The valve without spring return at the control spool (3) has no defined basic position in the de-energized condition. Without spring return with "OF" detent (only possible with symbols A, C and D) This version is a directional valve with two spool positions and two electronic solenoids with detent. The detents are used to lock the control spool (3) in the relevant spool position. During operation, continuous application of current to the electronic solenoid can thus be omitted which contributes to energy-efficient operation. Notices: Pressure peaks in the tank line to two or several valves can result in unintended movements of the control spool in the version with detent. We therefore recommend that separate return lines be provided or a check valve installed in the tank line. Due to the design principle, internal leakage is inherent to the valves, which may increase over the life cycle. Type 4WE 6 E6X/...E..XNK4... Throttle insert "...B" The use of a throttle insert is required when, due to prevailing operating conditions, flows occur during the switching processes, which exceed
