The REXROTH 4WEH16J7X/6HG24N9ETK4/B10 is a heavy-duty industrial directional spool valve engineered for pilot-operated control of start, stop, and direction of fluid flow in high-pressure hydraulic systems. This NG16 (CETOP 8 / ISO 4401-08) size valve features a J-type spool with closed-center characteristics, providing precise actuator positioning and load holding. The integrated high-performance wet-pin AC solenoid (24 V DC, 6HG24N9ETK4) ensures reliable, fast switching with low power consumption. The B10 designation indicates a high-capacity return spring for defined fail-safe spool return. Designed for continuous operation in demanding industrial environments, this valve offers excellent contamination tolerance and long service life.
