Bosch Rexroth 4WEH10E4X 6EW110N9ETSK4 Hydraulic Directional Valve

Bosch Rexroth 4WEH10E4X/6EW110N9ETSK4 is a four‑way hydraulic directional valve with electrohydraulic actuation, engineered to precisely start, stop, and direct oil flow in industrial hydraulic circuits. The EH designation indicates electrohydraulic actuation, and this model appears in Rexroth catalogs under multiple variant codes such as R901210246 and R901307677, with suffix variations like /6EW110N9ETK4/B10VSO8 and /6EW110N9ETK4/10B10 that reflect different electrical interfaces and configurations. Some listings note configurations suitable for subplate mounting, a common mounting approach in machine tools and automation systems. Power options vary by variant; for example, an available 230 VAC coil is shown on the /6EW230N9ETK4/B10 family variant, illustrating the range of control voltages offered for this series. There are substitution references for this part in Rexroth data, such as R901210284 replacing the original 4WEH10E4X/6EW110N9ETSK4/10 code, indicating ongoing data maintenance and equivalent catalog entries.
