Product description
Valves of type WN are fluidically actuated directional spool valves.
They control the start, stop and direction of a flow.
The directional valves basically consist of housing (1), one type of actuation (2.2) (hydraulic actuation cylinder), control spool (3) and one or two return springs (4).
When de-energized, 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 moved to the desired spool position by means of the types of actuation.
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.

Performance limits
(measured with HLP46, ϑOil = 40 ±5 °C)
Notice:
The specified performance limits are valid for operation with two directions of flow (e.g. from P to A and simultaneous return flow from B to T).
Due to the flow forces acting within the valves, the possible performance limit may be considerably lower with only one direction of flow (e.g. from P to A while port B is blocked).
The performance limits were determined when the solenoids were at operating temperature, at 10% undervoltage and without tank preloading.
