Product details

Rexroth Electro-Hydraulic Proportional Valve 4WRKE16E200L-3X/6EG24EK31/A1D3M

This is a high-precision, high-performance industrial control component designed for regulating the direction and flow of hydraulic fluids in hydraulic systems. Its core features include:

1. Control Precision:

• Integrates electrical position feedback and On-Board Electronics (OBE), combined with proportional solenoid actuation, to achieve linear correspondence between input signals (±10 V or 4–20 mA) and spool position.

• Offers high control accuracy with minimal dead band (≈1%), ideal for precision flow regulation.

2. Operating Parameters:

• Nominal diameter: 16 mm

• Maximum flow rate: 200 L/min

• Maximum operating pressure: 350 bar

• Compatible media: Hydraulic fluids such as mineral oil

• Temperature range: -20°C to +80°C

• Protection class: IP65 (dustproof and jet-water-resistant)

• Pollution-resistant design: Suitable for harsh environments.

3. Response Speed:

• Spring-centered spool designwith pilot-operated two-stage control architecture ensures short response times and stable dynamic performance.

• Optimized for high-speed industrial applications requiring rapid adjustments.

Applications:

Widely used in machine tools, construction machinery (e.g., hydraulic cylinders in excavators), marine steering systems, agricultural equipment, and more. It precisely controls the motion direction, speed, and pressure of hydraulic actuators, enabling complex automated processes. Its modular design simplifies installation and maintenance, making it a critical component in industrial automation systems.

Key Technical Notes:

• Electro-Hydraulic Actuation: Proportional solenoids ensure smooth, continuous control.

• Durability: Rated for continuous operation under demanding conditions.

• Interfacing: Supports both voltage and current input signals for flexibility in control systems.

This valve exemplifies Rexroth’s expertise in electro-hydraulic technology, delivering reliability and precision for mission-critical industrial applications.

Features:

• Direct-driven, controlled directional valve with servo-quality control spool and sleeve

• Single-sided operation, 4/4 fail-safe position in de-energized state

• Electronic position feedback and On-Board Electronics (OBE), factory-calibrated

• Electrical port with differential amplifier:

• Input options: A1 ± 10 V or F1 4...20 mA (Rsh = 200 Ω)

• Designed for electro-hydraulic control systems in production and test facilities

Specifications:

• Model: 4WRPEH10C3B100L2XG24K0A1M

• Type: Directional Control Valve

• Configuration: 4/4

• Electronics: Integrated OBE (On-Board Electronics)

• Control Mechanism: Spool/Sleeve

• Size: Size 10

• Flow Rate: 100 L/MIN (Linear Flow Characteristic)

• Power Supply: 24 V DC

• Connector: Without Mating Connector

• Command Input: ±10 V (Analog)

• Seals: NBR (Nitrile Butadiene Rubber)

Key Notes for Technical Accuracy:

1. Electro-Hydraulic Terminology: Retains industry-standard terms like "electro-hydraulic proportional valve" and "fail-safe position."

2. Electrical Port Clarity: Specifies input options (A1 ±10 V or F1 4...20 mA) with shunt resistor value (Rsh = 200 Ω).

3. Flow Characteristic: Emphasizes "linear" flow behavior for precise control applications.

4. Seal Material: Identifies NBR seals for compatibility with hydraulic fluids.
