The Bosch Rexroth 4WN10H5X//M (R901400837) is a pneumatically actuated industrial hydraulic valve that offers reliable performance for controlling the start, stop, and direction of fluid flow in hydraulic systems. This direct-actuated spool valve features a Symbol H spool symbol, designed for high-pressure applications with a maximum operating pressure of up to bar. It is suitable for various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC with NBR seals ensuring compatibility and durability.
The 4WN10H5X//M valve is characterized by its size and conforms to ISO porting patterns. It comes equipped with a subplate mounting connection diagram following the NFPA T.. R D SizeCETOP D standards. Furthermore, the unit has several ports and offers multiple switching positions to accommodate diverse hydraulic circuit requirements. The valve's actuation is achieved via pneumatic means, making it an effective solution for systems where electrical actuation is not viable or desired.
With its robust design and construction, this Bosch Rexroth valve ensures a maximum flow rate of l/min which can be regulated using an optional throttle insert when operating conditions demand it. The insert helps prevent excessive flows during the switching processes that could otherwise exceed the valve's performance limit. The product's weight reflects its sturdy build quality and capability to withstand demanding industrial environments.
Overall, the Bosch Rexroth 4WN10H5X//M valve stands out as a versatile component designed for efficient control within hydraulic circuits across various applications where dependable directional control of fluid flow is vital.

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: 4.700 kg
4/3-, 4/2- or 3/2-way version Porting pattern according to ISO 4401-05-04-0-05 Operating methods: Hydraulic
Valves of type WN 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) (hydraulic 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.

Type 4WN 10 E5X/…
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)
