The 4WEH10C4X/6EW110N9TDA valve is produced by Bosch Rexroth for the WEH Directional Spool Valves series. It directs hydraulic flow in automation circuits by shifting a 4-way, two-position spool that is returned by a spring when the solenoid is de-energized. The unit follows the ISO 4401-05-05-0-05 porting pattern so it mates with standard NG10 sub-plates, and its nominal size is NG10 to match medium flow manifolds. A maximum flow of 160 l/min can pass through the P, A, and B lines, while these pressure lines can withstand up to 280 bar during operation. The T port tolerates 160 bar so return side components must be rated accordingly. Pilot oil enters externally through port X and returns internally through port T, enabling remote pressure control without additional drain lines.
Pilot control functions between 10 bar and 250 bar, ensuring reliable actuation and protecting the housing from overload. The single solenoid operates on 110 V AC at 50 or 60 Hz, and a concealed manual override labeled N9 lets maintenance staff shift the spool without energizing the coil. The valve works in ambient temperatures from −20 °C to +50 °C, while the hydraulic fluid may range from −20 °C to +80 °C so equipment can run in varied climates. Overall mass is 6.4 kg which supports direct mounting on manifolds or frames without extensive bracing.
