Bosch Rexroth Hydraulic Proportional Valve
Description:
The Bosch Rexroth Hydraulic Proportional Valve is a high-performance electro-hydraulic control element that enables precise, continuously variable regulation of hydraulic flow, pressure, or direction. By using a proportional solenoid (often with integrated electronics / on-board amplifier), the valve converts an electrical input signal into a corresponding hydraulic output — enabling smooth, accurate control of actuators (cylinders or motors) in industrial and mobile hydraulic systems. Thanks to robust construction and tested reliability, Rexroth’s proportional valves are widely used in automation, mobile machinery, test rigs, and industrial hydraulics.

Advantages of the Bosch Rexroth Hydraulic Proportional Valve
-
Precise & Continuous Control — Proportional actuation allows smooth, infinitely variable adjustment of flow, pressure, or direction, rather than fixed on/off states.
-
Integrated Electronics & Feedback Options — Many valves come with on-board electronics (amplifier) and spool-position feedback, enabling high accuracy, repeatability, and ease of integration into electro-hydraulic control systems.
-
Wide Performance Range & Versatility — A broad portfolio: from small flow-control valves to high-performance directional spool valves, covering a wide spectrum of flow rates and pressures.
-
Standardized Mounting / Porting (ISO 4401 / Subplate) — Facilitates modular design, easier replacement or upgrade, and compatibility with manifolds/subplates.
-
Robustness and Reliability — Built to handle high pressure (315–350 bar), industrial hydraulic fluids, and rugged working conditions; backed by Bosch Rexroth’s long-term reputation in hydraulic components.
Noteworthy Features:
1. **Servo Quality Control**: This directly operated servo solenoid directional control valve features a control piston and sleeve built to servo quality standards, ensuring consistent and reliable performance.
2. **Fail-Safe Design**: Actuated on one side, the valve exhibits a 4/4 fail-safe position when switched off, enhancing safety and system reliability.
3. **Precise Control**: Electrical position feedback and factory-calibrated on-board electronics (OBE) guarantee accurate and consistent valve performance.
4. **Versatile Electrical Connection**: The valve offers flexible electrical connections, including a 6P+PE signal input differential amplifier with Interface A1 ±10 V or Interface F1 4…20 mA (Rsh = 200 Ω).
5. **Wide Applicability**: The Bosch Rexroth Hydraulic Proportional Valve finds its place in electrohydraulic controllers within production and testing systems, catering to a range of industrial needs.
