The Bosch Rexroth 4WRPEH10C3B50P-2X/G24K0/F1M (R901121806) is a high-response directional valve that is direct-operated with a control spool and sleeve in servo quality. This valve is designed for electrohydraulic controls within production and test systems, providing precise control and reliability. The integrated electronics feature allows for the comparison of the specified command value with the position actual value, enabling adjustments to be made in case of control deviations by activating the stroke solenoid. The stroke control cross-section of the Bosch Rexroth valve is proportionally controlled relative to the command value. When there's a presetting of command value, the electronics adjust the control spool against the spring to a central position. In its deactivated condition, the spring is untensioned to its maximum, ensuring that the valve remains in a failsafe position. In terms of switchoff behavior, this valve will move into a secured basic failsafe position when electronics are switched off. It may pass through an intermediate position (PBAT) which could result in movements in the controlled component; this should be taken into account during system design. The model features an electric position feedback system and factory-calibrated integrated electronics OBE. It comes with an electrical connection PPE and signal input differential amplifier with interfaces for both analog voltage (V) and current (mA) signals. The 4WRPEH10C3B50P-2X/G24K0/F1M operates on one side and ensures a failsafe position when switched off. This Bosch Rexroth high-response directional valve is notable for its robust construction including components like the control solenoid with position transducer, valve body, and mating connector. Its size and component series X can handle a maximum operating pressure (bar) alongside a nominal flow rate expressed in liters per minute (l/min), making it suitable for demanding hydraulic applications where precision and safety are critical.

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.
