***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth H-4WMM16H7X//V (R901437299) is a high-quality, manually actuated directional spool valve designed to regulate the start, stop, and direction of fluid flow within hydraulic systems. This particular model features a robust housing, a user-friendly hand lever for direct control of the spool, and one or two return springs ensuring the spool's return to its neutral or initial position when not engaged.
The H-4WMM16H7X//V valve is characterized by its manual operation facilitated through the hand lever which interacts directly with the control spool via a socket and bolt mechanism. This allows for precise movement from rest to the desired position. Once the hand lever is released, the return spring(s) automatically revert the control spool back to its rest state.
This model includes a detent mechanism that securely locks all spool positions in place, enhancing stability and reducing the risk of inadvertent flow changes. Additionally, it offers flexibility with options for spring return or detent positioning according to user needs.
Designed with protection against contaminants and moisture ingress, this valve ensures durability even in challenging environments. The head end with actuation mechanism can be exchanged without disassembly of the entire valve unit, promoting ease of maintenance and potential cost savings.
Equipped with porting patterns that conform to DIN form A and ISO standards, it supports maximum operating pressures up to bar and a maximum flow rate measured in liters per minute. For added functionality, this model can be fitted with inductive position switches and proximity sensors for contactless detection of spool positioning—further enhancing its operational capabilities.
The Bosch Rexroth H-4WMM16H7X//V (R901437299) represents a reliable solution for manual hydraulic flow control across various applications where precision and durability are paramount.

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).
