The Bosch Rexroth H-4WMM22H7X/ (R900247210) is a meticulously designed directional spool valve that offers manual actuation through a hand lever. This component is engineered to manage the start, stop, and direction of fluid flow within hydraulic systems. The valve's construction includes a robust housing, an ergonomic hand lever for ease of operation, a precise control spool, and one or two resilient return springs.
The H-4WMM22H7X/ valve operates by utilizing the hand lever to directly actuate the control spool. When not energized, the return springs maintain the control spool in either a central or initial position. Movement of the hand lever results in direct action upon the control spool via a socket and bolt mechanism, shifting it from its rest position to the selected end position. Upon releasing the hand lever, the return spring ensures that the control spool is returned to its original resting state.
This model incorporates features such as detents which serve to lock all spool positions securely in place—especially useful for maintaining consistent flow patterns during operation. The valve is designed with porting patterns that are compliant with DIN form A and ISO standards.
Additionally, this unit boasts protection against contamination and humidity for its actuation mechanism, enhancing durability and reliability in harsh working conditions. The head end of this valve is designed for easy exchange without necessitating full disassembly—increasing maintenance efficiency.
Equipped with options for inductive position switches and proximity sensors for contactless detection, this valve ensures precise control over hydraulic operations. It supports a maximum operating pressure of up to bar and can handle maximum flow rates of l/min.
The Bosch Rexroth H-4WMM22H7X/ represents an advanced solution in manual hydraulic flow control with its blend of durability, precision engineering, and user-friendly design.

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).
