The Bosch Rexroth 4WRSEH10V100LD-3X/G24K0/F1V (R901103271) is a high-response directional control valve with integrated control electronics designed for precise operation in hydraulic systems. This direct operated valve features a failsafe position held by compression springs when the solenoid is deenergized, ensuring reliable return to a safe state. The setup of this model includes a housing with connection surface, control spool within a sleeve, solenoid and cover, position transducer, and accessible zero-point adjustment. The 4WRSEH10V100LD-3X/G24K0/F1V operates by displacing the control spool proportionally to the electric input signal, allowing for smooth and continuous flow characteristics between ports P to A and B to T. This functionality makes it suitable for applications requiring precise position, velocity, and pressure control. Its electrical feedback system allows for high response sensitivity and minimal hysteresis. This Bosch Rexroth valve is designed for subplate mounting with porting patterns conforming to DIN form A and ISO standards. It has specifications including a size 10 component series X, maximum operating pressure of up to 315 bar, and nominal flow rates specified by the manufacturer. The integrated electronics OBE (On-Board Electronics) streamline setup and operation by eliminating the need for additional external control units. The model's capability to maintain mechanical central positions with deenergized solenoids ensures stability in system performance even when not actively controlled. The valve's design prioritizes both safety through its failsafe feature and efficiency through its direct operation mechanism, making it an essential component for sophisticated hydraulic applications that demand high levels of accuracy and reliability.

Direct operated high-response directional valve with integrated control electronics (OBE) for the control of flow direction and size Suitable for position, velocity and pressure control purposes Operation by means of control solenoids Electrical position feedback High response sensitivity and low hysteresis Integrated electronics (OBE) For subplate mounting: Porting pattern according to DIN 24340 form A and ISO 4401 With Fail-safe position for 4/4-directional control valve

4/4 directional design

In principle, the function of these valves corresponds to the function of the 4/3-way version. With de-energized solenoid, the control spool is, however, held in a fail-safe position by a compression spring.

The 4/4 directional control valves are designed as direct operated devices in plate design. Operation is effected by means of control solenoid. The solenoid is controlled via integrated control electronics.

Set-up:

The valve basically consists of:

Housing (1) with connection surface Control spool (2) in sleeve (3) with compression springs (4) Solenoid (5) and cover (6) Position transducer (7) Integrated control electronics (8) Zero point adjustment accessible via Pg9 (9)

Functional description:

With de-energized solenoid (5), fail-safe position of the control spool (2) by compression spring (4) Direct operation of the control spool (2) by energization of a control solenoid (5)

e.g. control of the solenoid

Displacement of the control spool (2) proportionally to the electric input signal Connection from P to A and B to T via orifice-type cross-sections with continuous or inflected linear flow characteristics

Switching off the solenoid (5) The compression spring (4) brings the control spool (2) back into the fail-safe position

The 4/3 and 4/4 directional control valves are designed as direct operated devices in plate design. Operation is effected by means of control solenoids. The solenoids are controlled via integrated control electronics.

Set-up:

The valve basically consists of:

Housing (1) with connection surface Control spool (2) in sleeve (3) with compression springs (4 and 5) Solenoids (6 and 7) Position transducer (8) Integrated control electronics (9) Zero point adjustment (10) accessible via Pg9

Functional description:

4/3 directional design

With de-energized solenoids (6 and 7), mechanical central position of the control spool (2) by compression springs (4 and 5) Direct operation of the control spool (2) by energization of a control solenoid

e.g. control solenoid "b" (7)

Displacement of the control spool (2) to the left, proportionally to the electric input signal Connection from P to A and B to T via orifice-type cross-sections with continuous or inflected linear flow characteristics Switching off the solenoid (7) The compression spring (4) brings the control spool (2) back into the central position

In the de-energized condition, the control spool (2) is held in a mechanical central position by the control springs. This position does not correspond to the hydraulic central position!

When the electric valve control loop is closed and with command value presetting 0 (0 V with A1 and/or 12 mA with F1), the control spool (2) is positioned in the hydraulic central position.
