Product details

The 4WRPEH6 high-frequency response proportional servo valve is a high-performance hydraulic control component manufactured by Bosch Rexroth. Below is a detailed introduction to its specific features:

I. Product Overview

• Type: Direct-acting proportional servo valve with a control piston and valve sleeve, featuring servo performance.

• Function: Used for precise control of flow and pressure in hydraulic systems, suitable for industrial applications requiring high dynamic response and precise control.

• Series: 4WRPEH series, NG6 specification.

II. Key Features

1. High-Frequency Response Characteristics:

• The valve spool reacts swiftly to control signals, rapidly adjusting the flow and pressure in the hydraulic system.

• High response frequency meets the demands of automated production lines, high-precision machine tools, and other applications requiring rapid response.

2. Precise Control:

• Utilizes advanced servo control technology for accurate position and speed control.

• Achieves precise adjustment of hydraulic system parameters to set values through sophisticated control algorithms and feedback mechanisms.

3. High Precision and Reliability:

• Demonstrates a high degree of immunity to disturbances, ensuring system stability and reliability even in harsh environments.

• The valve spool and sleeve are designed to servo quality standards, enhancing product durability and reliability.

4. Modular Design:

• Facilitates easy maintenance and component replacement. Users only need to replace damaged modules without disassembling and repairing the entire valve.

• Improves maintenance efficiency and reduces maintenance difficulty.

5. Built-in Electronics and Position Feedback:

• The control solenoid features position feedback with built-in electronics, improving control accuracy and response speed.

• The built-in amplifier is housed in a high-strength protective casing, providing strong vibration resistance and stable operation under severe conditions.

III. Technical Specifications

• Maximum Pressure: 31.5 MPa

• Maximum Flow Rate: 40 L/min (at a pressure differential of 7 MPa)

• Hysteresis: ≤0.2%

• Response Time: <10 ms

• Electrical Connection: 6P+PE, signal input differential amplifier with interface, input options include A1: ±10V, or interface F1: 4...20mA (Rsh=200Ω)

• Mounting Method: Plate mounting, mounting surface complies with ISO 4401-03-02 NG10 or ISO 4401-05-04 standards

IV. Application Scenarios

• Automated Production Lines: Used to control the motion speed and position of hydraulic cylinders for precise assembly and machining.

• High-Precision Machine Tools: In CNC machine tools, controls the spindle speed and feed rate to enhance machining accuracy and efficiency.

• Metallurgical Equipment: In continuous casting machines, rolling mills, and other equipment, controls the flow and pressure of hydraulic systems to ensure production stability and safety.

• Other Industrial Fields: Such as injection molding machines, die-casting machines, marine hydraulic systems, etc., where high dynamic response and precise control are required.
