4WE6D46-6X/OFEG24N9K72L/VSO407 AN

The 4WE6D46-6X/OFEG24N9K72L/VSO407 AN directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. Designed to route pressure, return, and actuator lines in hydraulic automation, it mounts on an ISO 4401-03-02-0-05 subplate so that installation aligns with common manifolds. The solenoid is rated at 24 V DC with a ±10 % voltage window and draws 8 W, a specification that simplifies power supply sizing and limits heat generation during operation. A 100 % ED duty cycle allows the coil to remain energized continuously without cooldown periods, while an M12×1 four-pin connector provides a quick electrical interface for control wiring. Hydraulically, the valve passes up to 60 l/min and withstands 315 bar at ports P, A, and B, enabling use in moderate-flow, high-pressure circuits. The enclosure meets IP65, sealing the coil and terminals against dust ingress and low-pressure water jets encountered in industrial environments.

Commissioning is aided by a concealed manual override that lets technicians shift the spool without electrical power when testing or bleeding a system. Fluid supplied to the valve should meet ISO 4406 class 20/18/15 so that particulate contamination does not score the lands or impede reliable switching. During sustained energization the coil surface may reach 85 °C, which requires surrounding components to tolerate elevated temperatures or be shielded. The design endures a 500 V switch-off overvoltage, reducing the need for external suppression when the controller de-energizes the coil. Tank port pressures up to 210 bar are supported, giving flexibility in circuits with pressurized returns. Total mass is 1.95 kg, light enough for direct mounting on compact manifolds yet substantial enough to resist vibration. Together these characteristics define a directional unit that manages return-line back-pressure, survives electrical transients, and offers manual intervention without removing the protective cap.
