The Bosch Rexroth 4WP10H5X//M/12 (R901426383) is a high-performance industrial hydraulic valve designed for reliable control of oil flow direction in hydraulic systems. This direct-actuated spool valve is part of the WP product group and is characterized by its size and symbol H, indicating its configuration and design. It features a UNF thread pipe connection for secure attachment to hydraulic circuits, ensuring compatibility with standardized components.
With a maximum operating pressure capacity, the 4WP10H5X//M/12 valve can handle demanding applications while maintaining precise control over the start, stop, and direction of fluid flow. Its pneumatic actuation allows for responsive and efficient operation, utilizing a pneumatic actuation cylinder to shift the control spool between positions. The inclusion of one or two return springs ensures that the spool returns to its central or initial position when de-energized.
This Bosch Rexroth valve accommodates various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC types. The seals are made from NBR (Nitrile Butadiene Rubber), offering good resistance to oil-based hydraulic fluids. For situations where operating conditions may cause excessive flow during switching processes, a throttle insert can be used with this valve to maintain performance within safe limits.
The 4WP10H5X//M/12 is designed for subplate mounting with an ISO standard porting pattern. It features multiple switching positions that provide flexibility in controlling fluid dynamics within hydraulic systems. This versatility makes it suitable for a wide range of applications where precise flow direction control is critical. The robust construction and reliable performance of this Bosch Rexroth industrial hydraulic valve make it an essential component in various hydraulic applications requiring high-quality directional control solutions.

Size 10, symbol H, pneumatically actuated
Industrial hydraulic valve in a high performance range. Reliable switch-over of the oil flow direction according to hydraulic symbol.
Unpacked Weight: 3.700 kg
4/3-, 4/2- or 3/2-way version Porting pattern according to ISO 4401-05-04-0-05 Operating methods: pneumatic
Valves of type WP are fluidically actuated directional spool valves.
They control the start, stop and direction of a flow.
The directional valves basically consist of housing (1), one type of actuation (2.2) (pneumatic actuation cylinder), 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) (except for version "O").
The control spool (3) is moved to the desired spool position by means of the types of actuation.
Throttle insert
The use of a throttle insert is required when, due to prevailing operating conditions, flows occur during the switching processes which exceed the performance limit of the valve.

Performance limits
(measured with HLP46, ϑOil = 40 ±5 °C)
Notice!
The specified performance 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 performance 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!

Notices!
Deviating from ISO 4401, port T is referred to as TA and port T1 is referred to as TB in this data sheet. The dimensions are nominal dimensions which are subject to tolerances. When screwing in/releasing the connection tube on the pilot oil port (9), the bushing (10) must be secured against twisting by using an open-end wrench.Subplates according to data sheet 45054 (separate order)
