***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth 4WRPEH6CB02L-3X/M/24A1 (R901382520) is an advanced, direct operated directional control valve designed with electrical position feedback and integrated electronics (OBE). This high-response valve is comprised of a housing with a control spool and sleeve of servo quality, a control solenoid with a position transducer, and the option for an electronics protection membrane. It features onboard electronics with either an analog or IOLink interface and can be optionally equipped with a damping plate.
The WRPEH valve operates by comparing the input command value to the actual spool position. If discrepancies are detected, it activates the stroke solenoid to adjust the control spool proportionally to the command value. In its default state or during deactivation, it employs failsafe positioning through spring tensioning. The valve's design ensures that it reverts to failsafe mode in cases such as under-voltage conditions or communication errors.
Incorporating a damping plate helps mitigate acceleration amplitudes affecting onboard electronics at frequencies above 50 Hz, although its use isn't recommended for predominantly low-frequency applications. The optional electronics protection membrane is particularly useful for preventing condensation within the OBE housing in environments with high humidity and temperature fluctuations.
This Bosch Rexroth valve is known for its reliability, energy efficiency (requiring no pilot oil), and flexibility across various applications including position, velocity, and pressure control. It boasts precise responsiveness with minimal hysteresis due to its high-quality construction. The product is suitable for systems requiring maximum operating pressures up to specified bars and nominal flow rates measured in liters per minute.

Valves type 4WRPEH are direct operated directional control valve with electrical position feedback and integrated electronics (OBE).
Set-up
The 4WRPEH high-response valve mainly consists of:
Valve housing with control spool and sleeve in servo quality (1) Control solenoid with position transducer (2) (optional with electronics protection membrane (5)) On-board electronics (OBE) (3) with analog or IO-Link interface (4) (optionally with damping plate (6))
Function
The integrated electronics (OBE) compares the specified command value to the position actual value. In case of control deviations, the stroke solenoid will be activated. Due to the changed solenoid force, the control spool is adjusted against the spring. Stroke/control spool crosssection is controlled proportionally to the command value. In case of a command value presetting of 0, 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.
Control solenoid shut-off
In case of the following faults, the control solenoids are de-energized by the integrated electronics (OBE) and the control spool is set to fail-safe position:
Falling below the minimum supply voltage Only at interface "F1": Falling below the minimum current command value of 2 mA (includes cable break of the command value line (current loop)) Only at interface "L1": Enable inactive, communication interruption (watchdog) In case of internal IO-Link error
Damping plate "D"
The damping plate reduces the acceleration amplitudes on the on-board electronics (frequencies >300 Hz).
Notice:
Use of the damping plate is not recommended for applications with mainly low-frequency excitation <300 Hz.
Electronics protection membrane "-967"
To prevent condensate formation in the housing of the integrated electronics (OBE), an electronics protection membrane (5) can be used.
Recommended for use outside industry-standard conditions with high ambient air humidity and significant cyclic temperature changes (e.g. outdoors).
For applications outside these parameters, please consult us!
