Product Overview
The Rexroth 4WEH 25 J6X/6E24N9ETSK4/B10V (Material No. R901298310) is a high-performance electro-hydraulic directional spool valve from the renowned Rexroth 4WEH series, size NG25. This pilot-operated, solenoid-actuated directional control valve is engineered to manage the start, stop, and direction of hydraulic fluid flow in demanding industrial circuits. The main spool is hydraulically piloted by a wet-pin DC solenoid directional valve, enabling reliable switching of high flow rates with minimal electrical power. The “J6X” designation indicates a spring-centered, spring-return spool with a specific flow pattern, while the “6E24N9ETSK4” pilot valve configuration provides 24 V DC solenoid actuation with an emergency manual override and integrated throttle/check provisions. Designed for subplate mounting in accordance with ISO 4401 and DIN 24340 standards, this valve delivers precise, repeatable control in high-pressure hydraulic systems up to 350 bar, making it a critical component in modern industrial automation and heavy machinery.
