The REXROTH 4WEH16 L7X/6EG24N9ETSK4/B10 is a heavy-duty industrial directional spool valve engineered for pilot-operated control of fluid flow direction, pressure, and start-stop in high-pressure hydraulic systems. This size 16 valve features a 4-way, 3-position spool with spring centering and a wet-pin AC solenoid system for reliable, repeatable actuation. The L7X designation indicates a specific spool type and flow characteristic, while the 6EG24N9ETSK4/B10 configuration includes a 24 V DC solenoid with manual override, an integrated throttle insert, and a concealed manual emergency operation. The valve conforms to ISO 4401 and CETOP mounting patterns, ensuring direct interchangeability with standard subplates and manifold interfaces.
