The Bosch Rexroth 4WMM 6 C5X/F SO43A-422 (R901311359) is a high-quality directional spool valve designed for controlling the start, stop, and direction of fluid flow within hydraulic systems. This model is part of the WM series and features a robust housing, a hand lever for manual actuation, and return springs that hold the control spool in its central or initial position when not engaged. The valve is equipped with a detent mechanism allowing each spool position to be locked as needed.
This particular valve model can be utilized in various applications requiring precise control over fluid dynamics. It is designed with a throttle insert to manage excessive flows that may occur during switching processes, ensuring the performance remains within the valve's capabilities. This insert is placed in channel P of the directional valve for optimal flow regulation.
The 4WMM 6 C5X/F SO43A-422 adheres to international standards with its porting pattern conforming to DIN form A without a locating hole and ISO with a locating hole. It provides flexibility in system design and integration due to these standardized mounting configurations.
In terms of specifications, this valve has a size component series X, which supports a maximum operating pressure of up to 350 bar and can handle maximum flow rates as defined by its design parameters. The model also supports additional functionalities such as inductive position switches and proximity sensors for contactless detection, enhancing its operational reliability and versatility in complex hydraulic systems.

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) (hand lever), 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.

Important information on hydraulic fluids! For further information and data on the use of other hydraulic fluids, please refer to data sheet 90220 or contact us! There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.)! The flash point of the hydraulic fluid used must be 40 K higher than the maximum solenoid surface temperature.Flame-resistant – containing water: Maximum pressure differential per control edge 50 bar. Pressure pre-loading at the tank port >20% of the pressure differential; otherwise, increased cavitation Life cycle compared to operation with mineral oil HL, HLP 50 to 100% |

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 limit 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!
