The Bosch Rexroth 4WRPEH6C3B02L-3X/M/24F1 (R901382336) is a high-response directional control valve designed for advanced hydraulic control applications. This valve is equipped with electrical position feedback and integrated onboard electronics (OBE), offering precise manipulation of fluid flow within hydraulic systems. The model features a valve housing, a control spool, and sleeve of servo quality, as well as a control solenoid with an integrated position transducer. It may also include an optional electronics protection membrane to safeguard against condensate formation in varying environmental conditions. The WRPEH series valve operates by comparing the command value to the actual spool position, adjusting the control spool via the solenoid force accordingly. The OBE ensures proportional stroke control relative to the input command value, maintaining high precision in operation. In the event of power loss or certain faults such as supply voltage drops or communication errors, the valve defaults to a failsafe position due to spring tension release, ensuring system safety. Additionally, this model can be optionally fitted with a damping plate that serves to reduce acceleration amplitudes affecting onboard electronics at frequencies above 20 Hz. However, it is not recommended for low-frequency applications under 20 Hz. This Bosch Rexroth valve is recognized for its reliable performance and robust design. It does not require pilot oil, making it energy-efficient. Its high-quality construction ensures long-lasting durability and responsiveness suitable for positioning, velocity, and pressure control tasks within hydraulic circuits. The unit's size and component series allow it to handle maximum operating pressures up to a specified bar level while facilitating a nominal flow rate measured in liters per minute (l/min). The optional IOLink interface enhances connectivity options for modern industrial applications requiring precise electronic communication for effective hydraulic system management.

Reliable - proven and robust design Safe - fail-safe position of the control spool in switched-off condition Energy-efficient - no pilot oil demand High quality - control spool and sleeve in servo quality Flexible - suitable for position, velocity and pressure control Precise - high response sensitivity and little hysteresis IO-Link interface, optional

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).
