The Bosch Rexroth 4WP 6 J6X/N/B10V/5 (R901364241) is a high-performance, direct-operated directional spool valve designed for precise control over the start, stop, and direction of fluid flow in hydraulic systems. This valve is characterized by its robust housing, pneumatic actuation cylinder, control spool, and return springs. The control ports are radially positioned to facilitate easy connection to the hydraulic circuit.
The model features a throttle insert for scenarios where operating conditions may cause flows that exceed the valve's performance limit during switching processes. This insert is placed in channel P to ensure smooth operation and enhanced control over flow rates.
In terms of design variations, this model comes without spring return but with a detent feature (version ..OF..), which allows each spool position to be securely locked. This makes it suitable for applications where maintaining a specific valve position is crucial even when de-energized. Additionally, there are versions without spring return and detent (version ..O..), where no defined spool position is maintained when the valve is not powered.
This particular model conforms to DIN form A porting pattern without a locating hole and ISO porting pattern with a locating hole. Subplates for mounting are available but must be ordered separately as indicated on the data sheet.
Furthermore, this Bosch Rexroth valve can accommodate inductive position switches and proximity sensors for contactless detection of the spool's position. It operates efficiently under a maximum pressure of up to bar and can handle maximum flow rates of l/min. Its component series X signifies that it belongs to a recent development series by Bosch Rexroth, ensuring compatibility with modern hydraulic systems and applications requiring precise fluid control.

General information
Valves of type WP 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 or two actuation elements (2) (pneumatic actuation cylinder), control spool (3) and one or two return springs (4). The ports for the control are positioned radially (5).
When de-energized, the control spool (3) is held in the central position or in the initial position by the return springs (4) (except impulse spool).
The control spool (3) is moved to the desired spool position by means of the actuation elements.
Throttle insert
The use of a throttle insert is required when due to prevailing operating conditions, flows can occur during the switching processes, which exceed the performance limit of the valve.
It is inserted in channel P of the directional valve.
Type 4WP 6 E6X/...
Without spring return, with detent,
version ..OF/..
Directional valves with pneumatic actuation are also available as a 2-spool position valve with detent (7). If actuation elements with detent are used, each spool position can be locked.
Without spring return,
version ..O/..
If actuation elements without return springs and without detent are used, there is no defined spool position in the de-energized state.

Minimum pilot pressure dependent on the tank pressure
At a higher tank pressure, the minimum pilot pressure has to be increased according to this diagram.
Performance limits
(measured with HLP46, ϑOil = 40 ±5 °C)
Notice!
The switching function of the valves is independent from the filtration due to the adhesive effect. To achieve the specified admissible flow values, a full flow filtration with 25 μm is recommended. The flow forces acting within the valves also influence the flow performance.
With 4-way directional valves, the specified flow data are therefore valid for normal operation with 2 directions of flow (e. g. from P to A and simultaneous return flow from B to T).
If there is only one direction of flow, the admissible flow may be significantly lower in critical cases (e. g. if a 4-way directional valve is used as a 3-way directional valve due to blocked port A or B).
