Rexroth 4WEH10E4X/6EG24N9ETK4/B10 Valve - FAQ

Q1: What is the main difference between a 4WEH and a standard 4WE valve?

A:​ The 4WEH is a two-stage, pilot-operated valve. A small, low-power solenoid valve (the pilot) controls hydraulic pressure to shift a larger main stage spool. This allows control of much higher flow rates (typically up to 100+ l/min) with a standard 24V DC signal, whereas a standard 4WE valve is directly solenoid-operated and handles lower flows.

Q2: How is the valve operated?

A:​ It is controlled by a double-solendoid pilot valve ("6EG24N9ETK4"). Energizing one of the two 24V DC solenoids on the pilot valve shifts the main spool to the corresponding position. De-energizing both solenoids allows springs to return the main spool to its center position. The "/B10" suffix often specifies the spring centering characteristics.

Q3: What are the typical applications for this type of valve?

A:​ It is used in medium-to-high flow hydraulic systems where precise directional control of large cylinders or motors is required, but where direct electrical control of a large valve would need a prohibitively large solenoid. Common in machine tools, presses, and large mobile equipment.

Q4: What are the key operating ratings?

A:​ Main stage maximum operating pressure is typically 315 bar. Maximum flow can be 100 l/min or higher, depending on the specific model. The nominal size is 10 mm. Always confirm the exact ratings for the E4X​ spool from the official datasheet.

Q5: Where can I find wiring diagrams and complete technical specifications?

A:​ For complete electrical data, pilot pressure requirements, shift time, flow curves, and the exact center position function of the E4X​ main spool, you must consult the official technical documentation for the specific order code R900952630.
