Product Overview
The Rexroth 4WEH16J7X/6EG24N9EK4 (Material No. R900927456) is a high-performance electro-hydraulic directional spool valve from the proven 4WEH series, size NG16 (Cetop 7 / ISO 4401-07). It is a two-stage valve design in which a pilot-operated solenoid valve controls the main spool of a hydraulically actuated directional valve, enabling the switching of large flow volumes with minimal electrical control power. Configured with a “J” type spool, the valve provides a tandem-center circuit function for precise directional control of actuators in demanding industrial hydraulic systems. The integrated design features a spring-centered main spool, wet-pin AC/DC solenoids with a nominal voltage of 24 V DC, an emergency manual override, and a built-in pilot oil supply and return arrangement, making it a direct-fit, high-reliability solution for manifold-mounted industrial power units.
