The Bosch Rexroth 4WH 10 J4X//V (R900960590) is a high-performance directional spool valve designed for efficient control of the start, stop, and direction of fluid flow within a hydraulic system. This particular model is characterized by its hydraulic actuation and spring centering feature, which ensures that the main control spool is held in the zero position by two return springs. The valve housing incorporates a main control spool that is directly actuated by pressurization and can be returned to its initial position either by springs or pressurization when the pilot pressure is relieved. The 4WH 10 J4X//V valve's functionality includes external pilot oil supply and return through channels X and Y, with the option for internal or external closing as per the requirements. It also features plug screws M according to DIN standards with varying wrench sizes for secure installation and maintenance. This model belongs to the WH type series of Bosch Rexroth valves, which are known for their reliability and adaptability to various hydraulic applications. The valve allows for subplate mounting with porting patterns conforming to ISO standards in 3- or 4-way versions. Users can benefit from additional customization options such as stroke setting, spool position monitoring, spring or pressure centering, along with spring end positioning or hydraulic end positioning. With a component series ranging from X to X, this directional valve can handle maximum operating pressures up to bar and accommodate maximum flow rates of l/min. Its versatility makes it suitable for a wide array of applications requiring precise fluid control in complex hydraulic systems.

Type of actuation: (external pilot control): Hydraulic For subplate mounting Porting pattern according toISO 4401 4/3-, 4/2- or 3/2-way version Spring or pressure centering, spring end position or hydraulic end position Optional versions:
- Stroke setting and/or spool position monitoring

Valve type WH is a directional spool valve with hydraulic actuation. It controls the start, stop and direction of a flow. The directional valve basically consists of the valve housing (1), the main control spool (2), one or two return springs (3.1) and (3.2) at valves with spring return or spring centering as well as the diversion plate (11). The main control spool (2) is actuated directly by pressurization. The main control spool (2) is held in zero or initial position by springs or pressurization. Pilot oil supply and return are external (see pilot oil supply).

4/3 directional valve with spring centering of the control spool

With this version, the main control spool (2) is held in zero position by two return springs (3.1) and (3.2). The two spring chambers (6) and (8) are connected to ports X and Y via the diversion plate (11). With pilot pressure loading of one of the two front sides of the main control spool (2), the spool is moved to the switching position. In the valve, the required ports are connected in this way. The spring on the opposite side returns the spool to the zero or initial position at pressure relief of the pressurized control spool area.

1)	If type WH is used in potentially explosion-proof areas, see data sheet 07011.
2)	The cleanliness classes specified for the components must be adhered to in hydraulic systems. Effective filtration prevents faults and simultaneously increases the life cycle of the components. For the selection of the filters, see www.boschrexroth.com/filter.
3)	For symbols C, F, G, H, P, T, V, Z, an internal pilot oil supply is only possible if the flow from P → T in the central position (for 3-spool position valve) or while crossing the central position (for 2-spool position valve) is so large that the pressure differential of P → T reaches a value of at least 6.5 bar.
4)	Spool S only for NG16
5)	For spools C, F, G,J, H, P, T, V, Z, S – by means of preload valve (not NG10) or correspondingly high flow. (Determination of the required flow, see preload valve)

Important notice on hydraulic fluids:

For more information and data on the use of other hydraulic fluids, please refer to the data sheets above or contact us. There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.). The ignition temperature of the hydraulic fluid used must be 50 K higher than the maximum solenoid surface temperature.

• Bio-degradable and flame-resistant:

If these hydraulic fluids are used, small amounts of dissolved zinc may get into the hydraulic system (700 mg zinc per pole tube).

Inductive position switch type QM: electrical connection

The electric connection is realized via a 4-pole mating connector (separate order) with connection thread M12 x 1.

Stroke setting, mounting options

The stroke of the control spool is limited by the stroke setting (1). The control spool stroke is shortened by loosening the lock nut (2) and clockwise rotation of the adjustment spindle (3). The control chamber (4) must be depressurized for this.

Notice:

The dimensions are nominal dimensions which are subject to tolerances.

Switching time adjustment

Type 4WEH 10 ..4X/…S

Type 4WEH 10 ..4X/…S2

The switching time of the main valve (1) is influenced by using a twin throttle check valve (2) (type Z2FS 6; data sheet 27506).

Modification of supply (3) to discharge control (4):

Remove the pilot control valve (5) – The plate (6) to accept the seal rings stays in place – Turn the switching time adjustment (2) around its longitudinal axis and put it back, install the pilot control valve (5).

Notice:

The modification may only be performed by authorized specialists or at the factory!

"D3” pressure reducing valve

Type 4WEH 10 ..4X/…/..D3

The pressure reducing valve (8) has to be used at a pilot pressure above 250 bar (with type 4WEH 22 …: 210 bar) and with version “H”.

The secondary pressure is kept at a constant level of 45 bar.

Notice:

If a pressure reducing valve "D3" (8) is used, a "B10" throttle insert has to be installed in channel P of the pilot control valve. The modification may only be performed by authorized specialists or at the factory!

The stipulations of the Machinery Directive 2006/42/EC are to be adhered to! Please also note data sheet 08012 with information on MTTFd values and shock and vibration loads!
