4WRLE10W80SJ Rexroth Proportional Valve 350 bar

Model Number	4WRLE10W-Z80SJ- 3X/G24K0/A1M

Product Description

Product Overview

The 4WRLE10W80SJ-3X/G24K0/A1M is a Bosch Rexroth pilot-operated proportional directional control valve with electrical position feedback and integrated on-board electronics (OBE).

The verified Bosch Rexroth model is:

4WRLE 10 W80SJ-3X/G24K0/A1M

with material number:

0811404702

Bosch Rexroth’s official historical product list directly associates material number 0811404702 with this exact model. The original wording “W-Z80SJ” should therefore be corrected to “W80SJ” for technical and SEO accuracy.

The 4WRLE family is designed for precise hydraulic flow-direction control and can be applied to position, velocity and pressure control. Rexroth specifies servo-quality control spool and sleeve construction in the pilot stage, together with electrical position feedback and integrated electronics.

For replacement applications, proper matching should include the hydraulic mounting interface, spool symbol, flow rating, pilot supply configuration and electrical command interface.

Displacement and Rotational Speed

Displacement: Not applicable; this is a directional control valve, not a hydraulic pump or motor.
Maximum Rotational Speed: Not applicable.

Key Technical Advantages

1. Pilot-Operated Architecture

The 4WRLE uses a two-stage pilot-operated architecture to control the main spool. This allows high-flow hydraulic circuits to be regulated with greater control resolution than a conventional simple switching valve.

The NG10 version provides a maximum flow capability of 300 L/min, while larger 4WRLE sizes extend the range substantially.

2. Electrical Position Feedback and OBE

Electrical position feedback and integrated electronics provide closed-loop spool-position control.

This architecture allows the valve to be integrated into hydraulic systems requiring accurate position, velocity or pressure control.

3. Servo-Quality Pilot Control Components

Rexroth specifies the pilot control spool and sleeve in servo quality, supporting precise proportional flow control and stable spool positioning.

4. Low Hysteresis and High Response Sensitivity

The official technical data specify:

Hysteresis: <0.1%
Response sensitivity: <0.05%
Range of inversion: <0.08%
Manufacturing tolerance: ≤10%

These values reflect the valve’s high-accuracy proportional control design.

5. Fast Dynamic Response

The NG10 configuration achieves an official 0–100% actuating time of 25 ms at X = 210 bar for the applicable spool symbols.

6. 24 VDC and ±10 V Command Interface

The specified A1M configuration uses a 24 VDC supply and ±10 V command value input, making it suitable for integration with industrial motion and hydraulic control systems.

Application Areas

Typical applications include:

Injection molding machines
Hydraulic presses
Forging equipment
Machine tools
Steel and metallurgical equipment
Industrial hydraulic power units
Automated hydraulic actuators
Hydraulic cylinder position control
Hydraulic motor speed control
Closed-loop pressure control systems
High-performance industrial hydraulic systems

Bosch Rexroth specifically positions the 4WRLE series for position, velocity and pressure control applications.

Expert Maintenance Tips

1. Verify Pilot Supply Pressure

Because the 4WRLE is pilot-operated, insufficient pilot pressure can lead to slow spool movement, unstable control or inadequate flow. The official minimum pilot pressure is 10 bar.

2. Do Not Publish 80 L/min as the Universal Maximum Flow

The 80SJ designation should not automatically be interpreted as a universal maximum valve flow of 80 L/min.

For NG10, Rexroth specifies 60/100 L/min rated flow at Δp = 5 bar/control edge, while the maximum flow is 300 L/min. Actual flow depends on the pressure differential and the selected hydraulic characteristics.

3. Maintain Hydraulic Cleanliness

The specified fluid cleanliness class is ISO 4406 Class 18/16/13. Proper filtration is essential for protecting the precision pilot-stage components and maintaining stable proportional control.

4. Verify the A1 Command Interface

The A1 version uses a ±10 V command input. Do not substitute an F1 4–20 mA version without checking the control system architecture. Rexroth’s current selector explicitly distinguishes A1, F1, L1 and C6 interfaces.

5. Check Fail-Safe Behavior

After electrical shut-off, the pilot valve enters its fail-safe position and the main valve moves to its specified spring-centered position. The exact behavior depends on the hydraulic symbol.

6. Verify Legacy 3X-to-Current 4X Replacement

The specified 4WRLE10W80SJ-3X/G24K0/A1M belongs to the 3X component series. Current Rexroth documentation includes the 4X generation, so any replacement should be verified against the complete ordering code and mounting/interface requirements rather than the family name alone.
