The Bosch Rexroth H-4WMM22V6X/F (R978900501) is a high-quality, manually actuated directional spool valve designed for controlling the start, stop, and direction of fluid flow within hydraulic systems. This model features a robust housing, an ergonomic hand lever for direct actuation of the control spool, and one or two return springs that ensure the spool returns to its rest position when not engaged. The valve offers precise control over hydraulic circuits with its straightforward manual operation.
Equipped with a detent mechanism, the H-4WMM22V6X/F locks the control spool in place for each of the designated spool positions, providing stability and reliability in maintaining selected flow paths. This feature is particularly useful in applications where constant flow or specific directional control needs to be maintained without continuous operator engagement.
Designed with durability in mind, the valve's actuation mechanism is shielded against contaminants and moisture, prolonging its service life even in harsh environments. Additionally, the head end with the actuation mechanism can be exchanged without disassembling the entire valve unit, facilitating easy maintenance and potential upgrades.
The H-4WMM22V6X/F follows porting patterns according to DIN form A and ISO standards, ensuring compatibility with a wide range of equipment and simplifying installation processes. The valve operates effectively at a maximum pressure of up to 315 bar and can handle maximum flow rates up to 160 liters per minute.
This model also supports optional enhancements such as inductive position switches and proximity sensors for contactless detection of spool position—a valuable feature for automated systems requiring precise feedback on valve status. With its combination of manual flexibility and potential for integration into automated settings, this Bosch Rexroth directional spool valve is an essential component for various hydraulic applications demanding reliable manual control with options for system monitoring.

Valves type WMM are manually actuated directional spool valves. They control the start, stop and direction of a flow and basically consist of housing (1), hand lever (2), 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). The control spool (3) is actuated directly by the hand lever (2). By means of a socket and the bolt (5), it acts directly on the control spool (3) which is thereby moved from its rest position to the desired end position.
When the hand lever (2) has been reset to spool position zero, the return spring (4) pushes the control spool (3) back to its rest position again.
Type H-4WMM../F.. (with detent)
This version is a directional valve with 2 or 3 spool positions and a detent (6) which locks all spool positions.

Attention!
The switching function of the valves is independent from the filtration due to the adhesive effect. To achieve the specified admissible flows, 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 flows 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 (e. g. if a 4-way directional valve is used as a 3-way directional valve due to blocked port A or B).
