The Bosch Rexroth 4WRPEH6C3B24L-3X/M/24F1 (R901382349) is a high-performance industrial hydraulic valve designed for reliable control of oil flow direction, featuring a spool valve that is directly actuated. This valve is equipped with an internal piston position feedback system, ensuring high accuracy and precision in operation. It includes a safety shutdown mechanism with an additional failsafe position, enhancing the safety features of the product. The 4WRPEH valve has a maximum pressure rating and comes with an electrical connection that utilizes a connector pole PE according to EN standards. It is actuated electrically with integrated electronics, and it supports subplate mounting for secure installation. The valve follows NFPA T..R D SizeCETOP D and ISO connection diagrams, indicating its compliance with industry standards. Designed for analog connectivity, the command value can be controlled via a 4-20 mA signal. The WRPEH series valves are direct-operated directional control valves with electrical position feedback and integrated onboard electronics (OBE), which can be interfaced with analog or IOLink connections. The optional damping plate reduces acceleration amplitudes on the onboard electronics for frequencies above 50 Hz, while the electronics protection membrane is recommended for conditions outside industry-standard environments to prevent condensate formation. This product adheres to CE conformity as well as electromagnetic compatibility EU directives, RoHS Directive EU, and REACH Regulation EC no., ensuring its compliance with European Union regulations regarding safety and environmental impact. The valve's seals are made from NBR and are compatible with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. In summary, the Bosch Rexroth 4WRPEH6C3B24L-3X/M/24F1 offers precise control in hydraulic systems through its robust design featuring electrical actuation with integrated electronics for accurate oil flow direction management in various industrial applications.

Description

PROPORTIONAL DIRECTIONAL VALVE 4WRPEH6C3B24L-3X/M/24F1

Size 6, symbol C3, electrical with integrated electronics 24 V DC

Industrial hydraulic valve in a high performance range. Reliable control of the oil flow direction according to hydraulic symbol. High accuracy thanks to internal piston position feedback

Unpacked Weight: 2.98234 kg

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).
