The REXROTH 4WEH 16 D72/6HG24N9ETK4/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 size 16 valve features a 4-way, 3-position design with a D72 spool type, spring return, and a 24 V DC wet-pin solenoid with integrated manual override. The N9 design indicates a high-performance solenoid with a nominal voltage of 24 V DC and a rectifier integrated into the coil, ensuring reliable switching even under fluctuating supply conditions. The ETK4 designation specifies an external pilot oil supply and external pilot oil return, while the B10 indicates a high-pressure pilot stage with a maximum pilot pressure of 100 bar. The valve is designed for subplate mounting according to ISO 4401-07, CETOP 7, and NFPA T3.5.1 R2/DIN 24340 A16 patterns, providing a compact and robust solution for demanding industrial applications.
