The Bosch Rexroth 4WRPEH10C3B100L-2X/G24K0/F1M (0811404817) is a high-response directional valve that is direct operated with a control spool and sleeve of servo quality. Designed for electro-hydraulic control applications, this valve features integrated electronics, including an electric position feedback system and factory-calibrated onboard electronics (OBE). It operates with a single-sided 4/4 fail-safe position when the electronics are switched off, ensuring immediate movement to a secured basic position for safety. This model includes a control solenoid with a position transducer, which allows for precise control by comparing the specified command value with the actual valve position. Adjustments to the control spool are made through changes in magnetic force to correct any deviations. The valve's stroke/control cross-section is proportionally controlled based on the command value input. With a preset command value of 0 V, the valve automatically adjusts to a central position. For electrical connections, it features a 6P+PE connector and offers two interface options: "A1" which accepts ±10 V or "F1" which uses 4 ... 20 mA signals (with Rsh = 200 Ω). This flexibility makes it suitable for various electro-hydraulic controls in production and test systems. The switch-off behavior of this valve is critical for system design considerations as it dictates the fail-safe positioning that occurs during power loss or electronic shutoff. The movement through P–B/A–T positions under these circumstances can cause movements in the controlled component that must be accounted for in system planning. Overall, the Bosch 4WRPEH10C3B100L-2X/G24K0/F1M provides precision and reliability for demanding applications requiring accurate electro-hydraulic controls.

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.
