  Type WE valves are solenoid-operated directional spool valves used for controlling the start, stop, and direction of fluid flow.
  These directional control valves consist of a housing (1), one or two solenoids (2), a control spool (3), and one or two return springs (4).
  In the de-energized state, the control spool (3) is held in the neutral or initial position by the return springs (4), except for impulse spools. The control spool (3) is actuated via wet pin solenoids (2).
  To ensure proper operation, it's important to make sure that the solenoid pressure chamber is filled with oil.
  The control spool (3) moves to the desired position when the solenoid (2) and push rod (5) are activated. This allows free flow from P to A and B to T, or P to B and A to T.
  When the solenoid (2) is de-energized, the control spool (3) returns to its original position due to the return springs (4).
  Solenoids can also control the spool using an optional override button (6) under de-energized conditions.
  There are different versions available, such as Type 4WE 6.. L6X/O... (only for symbols A, C, and D), which has two positions and two solenoids without a detent.
  Type 4WE 6.. L6X/OF... (impulse spool, only for symbols A, C, and D) includes a detent, allowing both positions to be fixed alternately, so the solenoid doesn’t need to stay energized continuously.
  A cartridge throttle (type 4WE 6..L6X/¡-/B..) may be necessary if the actual flow exceeds the valve’s performance limits during switching.
  This throttle is installed in the P channel of the directional control valve.
  For applications with voltage pulsation, solenoids with a wide voltage range are recommended.
  For high protection grade environments, a waterproof plug should be used.
