They control the start, stop and direction of a flow. The directional valves basically consist of the housing (1), one or two 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 impulse spools). The control spool (3) is actuated by wet-pin solenoids (2). For unobjectionable functioning, the hydraulic system has to be bled properly. The force of the 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 → A and B → T or P → B and A → T. After de-excitation of the solenoid (2), the return spring (4) pushes the control spool (3) back to its rest position. An optional manual override (6) allows 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 solenoids without detent. In the de-energized condition, there is no defined spool position. With spring return "OF" (impulse spool, only possible with symbols A, C and D) This version is a directional valve with two spool positions, two solenoids and one detent. It alternately locks the two spool positions and the solenoid therefore does not need to be permanently energized. Notice: Please observe a possible pressure conversion in the event of a differential cylinder. If pressure is led to the chamber on the piston side and the outflow of hydraulic fluid is blocked from the chamber on the rod side, it might lead to a pressure intensification and inadmissible high pressure on the rod side. This can damage cylinders, supply lines and connected valves. Type 4WE 6 E6X/.E..NXE... Throttle insert The use of a throttle insert is required when, due to prevailing operating conditions, flows occur during the switching processes which exceed the performance limit of the valve.
