The Bosch Rexroth 4WRPEH10C4B100L-2X/G24K0/A1M (0811404803) is a high-response directional valve, designed for precise control in electro-hydraulic systems. It features direct operation with a control spool and sleeve of servo quality, ensuring reliable performance in production and test system applications. The valve operates with one side actuation and defaults to a 4/4 fail-safe position when switched off, providing an essential safety feature for system design considerations.
This model is equipped with an electric position feedback mechanism and integrated electronics (OBE), which are factory calibrated for immediate use upon installation. The electronics facilitate the comparison of the command value with the actual position value, adjusting the stroke solenoid as needed to correct any deviations by changing the magnetic force, which in turn adjusts the control spool against a spring.
The valve's switch-off behavior ensures that it will move into a secured basic fail-safe position when the electronics are turned off. During this transition, it passes through the P–B/A–T positions, potentially causing movements in the controlled component—a factor that must be taken into account during system design.
Additionally, this Bosch valve includes a control solenoid with a position transducer for enhanced accuracy, a robust valve body for durability, and a mating connector for simplified electrical integration. It offers an electrical connection of 6P+PE and accepts signal input through differential amplifier interfaces "A1" ±10 V or "F1" 4 to 20 mA (Rsh = 200 Ω). Its design and capabilities make it well-suited for use in sophisticated electro-hydraulic controls where precision and reliability are paramount.

General information
In the integrated electronics, the specified command value is compared with the position actual value. In case of control deviations, the stroke solenoid will be activated which - due to the changed magnetic force - adjusts the control spool against the spring.
Stroke/control cross-section is controlled proportionally to the command value. In case of a command value presetting of 0 V, the electronics adjusts the control spool against the spring to central position. In deactivated condition, the spring is untensioned to a maximum and the valve is in fail-safe position.
Switch-off behavior
With switched-off electronics, the valve will immediately move into the relevant secured basic position (fail-safe). In this connection, it moves through the position P–B/A–T which may result in movements at the controlled component. This has to be considered in the system design.

Notice:
Supply voltage 24 VDCnom, if 18 VDC are undershot, there will be an internal fast shut-down, comparable to “Enable OFF”.
Additionally with version “F1”:
ID – E ≥ 3 mA – Valve is active
ID – E ≤ 2 mA – Valve is deactivated.
Electrical signals provided via control electronics (e. g. actual value) must not be used to switch off safety-relevant machine functions. (See also the European standard "Safety requirements for fluid-powered systems and their components - Hydraulics", EN 982!)
