***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 4WRSE10V50-3X/G24K0/A1V-280 (R900945323) is a high-response directional control valve designed for precise control of flow direction and size in hydraulic systems. This direct operated valve is ideal for applications requiring accurate position and velocity control, ensuring high response sensitivity and low hysteresis. The valve is equipped with integrated control electronics OBE, which allow for seamless operation via control solenoids. The 4WRSE10V50-3X/G24K0/A1V-280 features a robust housing with a connection surface, a control spool balanced by compression springs, and solenoids that are controlled through the integrated OBE. The zero point adjustment is easily accessible through the Pg cover, adding to the user-friendly design of the valve. When the solenoids are deenergized, the control spool remains in a mechanical central position due to the return springs. However, when the electric valve control loop is closed, it moves to the hydraulic central position. This particular model has a porting pattern that complies with DIN form A and ISO standards, making it suitable for subplate mounting. With its size 10, component series X can handle a maximum operating pressure of 280 bar and has a maximum flow capacity of 50 l/min while maintaining a nominal flow rate of l/min. Overall, the Bosch Rexroth 4WRSE10V50-3X/G24K0/A1V-280 exemplifies precision engineering for demanding hydraulic applications where exacting flow control is essential. Its direct operation by means of solenoid activation coupled with electrical position feedback ensures consistent performance and reliability in various operational contexts.

Direct operated high-response directional valve with integrated control electronics (OBE) for the control of flow direction and size Suitable for position and velocity control 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

The 4/3 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 (OBE).

Set-up:

The valve basically consists of:

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

Functional description:

With de-energized solenoids (5 and 6), central position of the control spool (2) by compression springs (3 and 4) Direct operation of the control spool (2) by energization of a control solenoid

e.g. control solenoid "b" (6)

Displacement of the control spool (2) to the left, proportionally to the electric input signal Connection from P → A and B → T via orifice-type cross-sections with linear flow characteristics Switching off the solenoid (6)

The compression spring (3) 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 return springs of the solenoids. With control spool symbols “V” and “Q”, this position does not correspond to the hydraulic central position! When the electric valve control loop is closed, the control spool (2) is positioned in the hydraulic central position.
