The Bosch Rexroth 4WRLE16E1-250LJ-4X/MXY/24A1 (R901404333) is a high-performance industrial hydraulic valve that offers reliable control of oil flow direction in accordance with its spool symbol E. This pilot-operated spool valve features electrical actuation with integrated electronics (OBE), providing high accuracy through internal piston position feedback. Designed for subplate mounting, the valve conforms to CE electromagnetic compatibility, EU RoHS Directive, and REACH Regulation EC standards. The 4WRLE16E1-250LJ-4X/MXY/24A1 is characterized by its linear characteristic curve and accommodates external pilot oil supply and return. It supports a maximum operating pressure of up to bar and ensures a nominal flow rate of l/min, with the capability to handle a maximum flow of l/min. The valve's connectivity options include an analog command value input of V and it operates on a supply voltage of VDC. Equipped with NBR seals, this hydraulic valve is compatible with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC. Its robust design ensures safety and quality in applications requiring precise control of position, velocity, or pressure. The unit's failsafe feature positions the control spool in a spring-centered central or offset position when deactivated. This model includes additional features such as an optional damping plate for reducing acceleration amplitudes above Hz frequencies and an electronics protection membrane recommended for use in environments with high humidity or significant temperature fluctuations. Overall, the Bosch Rexroth 4WRLE16E1-250LJ-4X/MXY/24A1 valve offers flexibility and precision for sophisticated hydraulic control applications requiring robust performance and compliance with stringent European standards.

PROPORTIONAL DIRECTIONAL VALVE 4WRLE16E1-250LJ-4X/MXY/24A1

Size 16, symbol E1, electrical with integrated electronics, 24 V DC

Industrial hydraulic valve in the high performance range; reliable control of the oil flow direction according to the hydraulic symbol; high accuracy through internal piston position feedback

Unpacked Weight: 11.940 kg

Reliable - proven and robust design Safe
- The control spool of the pilot control valve is in the “fail-safe” position when the unit is switched off
- The control spool of the main valve is in the spring-centered central position and/or in the offset position High quality – control spool and sleeve of the pilot control valve in servo quality Flexible - suitable for position, velocity and pressure control Precise - high response sensitivity and little hysteresis IO-Link interface, optional

Symbol E. and W.

The valve type 4WRLE is a pilot-operated directional control valve with electrical position feedback and on-board electronics (OBE).

Layout

The valve basically consists of 3 main assemblies:

Pilot control valve (1) with control spool and sleeve, return spring, control solenoid and inductive position transducer (optional with electronics protection membrane (5) and damping plate (4)) Main valve (2) with centering spring and position feedback On-board electronics (OBE) (3) with analog or IO-Link interface (6)

Function

When the on-board electronics (OBE) are switched off or inactive, the control spool of the pilot control valve is spring-operated in the "fail-safe" position. The control spool of the main valve is its spring-centered central position.

The on-board electronics (OBE) compare the specified command value to the position actual value of the main valve control spool. In case of control deviations, the control solenoid will be activated. Due to the changed magnetic force, the pilot control spool is adjusted against the spring.

The pilot oil supply in the pilot control valve is either internal via port P or external via port X. The feedback can be internal via port T or external via port Y to the tank.

Control solenoid shut-off

In case of the following errors, the control solenoids are de-energized by the on-board electronics (OBE), the pilot control spool is set to “fail-safe” position and unloads the pilot oil chambers of the main valve. Operated by the spring, the main valve control spool will move to the central position.

Falling below the minimum supply voltage Only with interface "F1": Falling below the minimum current command value of 2 mA (includes cable break of the command value line (current loop)). Only with interface "L1": Enable inactive, communication interruption (watchdog) In case of internal IO-Link error Only with interface "C6": Additionally enable inactive

Damping plate "D"

The damping plate (4) reduces the acceleration amplitudes on the on-board electronics (frequencies >300 Hz).

Notice:

Use of the damping plate is not recommended for applications with mainly low-frequency excitation <300 Hz.

Electronics protection membrane "-967"

To prevent condensate formation in the housing of the on-board electronics (OBE), an electronics protection membrane (5) can be used.

Recommended for use outside industry-standard conditions with high ambient air humidity and significant cyclic temperature changes (e.g. outdoors).

Notice:

Pilot-operated 4/3-directional control valves with positive overlap are functional in controlled or regulated axes. The overlap in the de-energized state is approx. 20% of the control spool stroke. While the electrical supply voltage is switching off, the drive may be accelerated for a short time in functional direction P to B.

Symbol V and V1-

The valve type 4WRLE is a pilot-operated directional control valve with electrical position feedback and on-board electronics (OBE).

Layout

The valve basically consists of 3 main assemblies:

Function

The flow which is activated via the control cross-sections leads to an adjustment of the main control spool. The stroke/control cross-section of the main control spool is regulated proportionally to the command value. In case of a command value presetting of 0 V, the electronics adjust the control spool of the main valve to central position.

The pilot oil supply in the pilot control valve is either internal via port P or external via port X. The feedback can be internal via port T or external via port Y to the tank.

Control solenoid shut-off

Damping plate “D” and electronics protection membrane “-967”

See “symbol E. and W.”:

Notice:

Pilot-operated 4/3 directional control valves are only functional in the active control loop and do not have a locking basic position when deactivated. Consequently "external isolator valves" are required in many applications and must be taken into account regarding the switch-on/switch-off order. While the electrical supply voltage is switching off, the drive may be accelerated for a short time in functional direction P to B.

Important information on hydraulic fluids: For more information and data on the use of other hydraulicfluids, 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 surface temperature. Bio-degradable and flame-resistant – containing water: If this hydraulic fluid is used, small amounts of dissolved zinc may get into the hydraulic system. Flame-resistant - containing water: Due to increased cavitation tendency with HFC hydraulic fluids, the life cycle of the component may be reduced by up to 30% as compared to the use with mineral oil HLP. In order to reduce the cavitation effect, it is recommended - if possible specific to the installation - to back up the return flow pressure in ports T to approx. 20% of the pressure differential at the component. Dependent on the hydraulic fluid used, the maximum ambient and hydraulic fluid temperature must not exceed 50 °C. In order to reduce the heat input into the component, the command value profile is to be adjusted for proportional and high-response valves.
