The Bosch Rexroth 3WMR6A5X (R900471414) is a high-performance industrial hydraulic valve designed for manual operation, featuring a size D configuration and a spool symbol A. This directional control valve is capable of reliably switching the oil flow direction, accommodating a maximum pressure as specified by the product group ID. It includes multiple ports and offers manual actuation through a roller plunger mechanism. Constructed with NBR seals, the 3WMR6A5X valve is compatible with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC. The robust housing contains the control spool and one or two return springs that hold the spool in its central or starting position when de-energized. When manually actuated with a detent, this allows for precise control over the start, stop, and direction of fluid flow. For applications requiring specific locking positions, this model comes equipped with a detent mechanism that secures each spool position. Additionally, it has provisions for throttle inserts in channel P to manage any excessive flows during switching processes that may surpass the valve's performance limit. The 3WMR6A5X follows porting patterns according to DIN without locating holes and ISO standards with locating holes. It supports various configurations including 2-way or 3-way versions and can be mounted using a subplate connection based on NFPA T.. R D SizeCETOP D or ISO connection diagrams. This model also accommodates inductive position switches and proximity sensors for contactless signaling. With its robust design and versatile capabilities, the Bosch Rexroth 3WMR6A5X manual hydraulic valve is an essential component for industrial applications requiring precise fluid control through manual manipulation.

DIRECTIONAL SPOOL VALVE 3WMR6A5X/

Size 6, symbol D, manually operated

Industrial hydraulic valve in a high performance range. Reliable switch-over of the oil flow direction according to hydraulic symbol.

Unpacked Weight: 1.160 kg

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: Roller plunger 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) (roller plunger), 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!
