The Bosch Rexroth 4WMDA6D5X/F (R900468573) is a high-quality directional spool valve designed for controlling the start, stop, and direction of fluid flow within hydraulic systems. This particular model is part of the WM series of valves, which are recognized for their robust construction and precise control capabilities. The 4WMDA6D5X/F features a lockable rotary knob actuation mechanism that allows for easy manual operation. With its detent design, each position of the control spool can be securely locked into place to ensure consistent performance.
This valve is equipped with one or two return springs that hold the control spool in a central or starting position when in a de-energized state. When actuated, the control spool shifts to the desired position smoothly and efficiently. For applications where excessive flow during switching processes could surpass the valve's performance limit, a throttle insert can be added in channel P to moderate the flow.
The 4WMDA6D5X/F offers versatility through its 3 or 4-way version options and adheres to porting patterns according to DIN form A without locating holes and ISO with locating holes. The valve also supports inductive position switches and proximity sensors for contactless detection of spool position.
With a maximum operating pressure of 350 bar and a maximum flow rate of up to 120 liters per minute, this component is suitable for various demanding hydraulic applications. Its size and component series X underscore its capacity to handle substantial operational demands while maintaining precision. Overall, the Bosch Rexroth 4WMDA6D5X/F is an essential component for hydraulic systems requiring reliable directional control with manual actuation.

Type WM.. valves are mechanical, manually actuated directional spool valves. They control the start, stop and direction of a flow. Directional valves basically consist of housing (1), one type of actuation (2) (lockable rotary knob), control spool (3) and one or two return springs (4). In de-energized state, the return springs (4) maintain the control spool (3) in central or starting position - if the rotary knob is actuated with a detent. The control spool (3) is moved to the desired spool position by means of the type of actuation (2).
Detent
Directional valves with rotary knob are generally designed with detent. Directional valves with hand lever are optionally available as 2 or 3 position valves with detent. Directional valves with roller plunger are generally designed without detent. If types of actuation with detent are used, each spool position can be locked, depending on the valve type.
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.

Performance limits
(measured with HLP46, ϑOil = 40 ±5 °C)
Notice!
The specified switching power limits are valid for use 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 admissible switching power limits may be considerably lower with only one direction of flow (e. g. from P to A while port B is blocked)!
In such use cases, please consult us
