The Bosch Rexroth 4WMM6H5X/F (R900472755) is a high-quality directional spool valve designed for precise control of fluid flow in hydraulic systems. This manually actuated valve features a hand lever for operation, allowing users to start, stop, and change the direction of flow with ease. The robust construction includes a housing, a control spool, and one or two return springs that ensure the spool remains in its central or initial position when not engaged. Equipped with a detent mechanism, the 4WMM6H5X/F valve allows each spool position to be securely locked in place, providing reliable performance in various applications. This feature is particularly useful when consistent flow direction is necessary for the operation of machinery or equipment. Furthermore, the 4WMM6H5X/F model incorporates a throttle insert within channel P to manage excessive flows that may occur during switching processes. This insert safeguards the valve against performance limits being exceeded due to operating conditions, thereby extending the lifespan of the valve and maintaining system efficiency. This Bosch Rexroth valve adheres to stringent industry standards with its porting pattern conforming to DIN form A without a locating hole and ISO with a locating hole. It supports various way configurations and offers compatibility with inductive position switches and proximity sensors for contactless detection. The 4WMM6H5X/F has impressive operational specifications including a maximum operating pressure of up to 350 bar and can accommodate maximum flow rates as required by specific applications. With its versatility and durable design, this Bosch Rexroth directional spool valve is an essential component for hydraulic system operators seeking reliable and precise fluid control.

4/3-, 4/2- or 3/2-way version Porting pattern according to DIN 24340 form A (without locating hole) Porting pattern according to ISO 4401-03-02-0-05 (with locating hole) Type of actuation: hand lever Inductive position switch and proximity sensors (contactless)

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.

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!
