The 4WE6D6X/OFEG24N9K73L directional spool valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth. It directs hydraulic flow in automation circuits where electrically actuated shifting increases system flexibility. The valve employs a D/OF detent spool so the selected position is mechanically held until the solenoid receives another command. Its porting pattern follows ISO 4401-03-02-0-05, allowing direct mounting on standard NG6 sub-plates without additional adapters. To interface with control wiring, the coil uses an M12×1 four-pole connector designated K73L. Electrical data include a nominal voltage of 24 V DC and a rated current of 1.25 A, which together define a nominal power draw of 30 W during steady energization. The coil accepts a ±10 % voltage deviation so it tolerates normal supply variation in mobile or industrial panels. Continuous energization is allowed because the coil is specified for a 100 % duty cycle. Environmental sealing reaches IP65, so the enclosure resists dust and low-pressure water jets when the connector is properly installed.
In service, the valve handles pressures up to 350 bar at ports P, A, and B, enabling use in high-pressure circuits. The return line may reach 210 bar at port T when direct-current actuation is employed. Flow capacity is 80 l/min under direct-current operation, delivering adequate throughput for typical NG6 manifolds. The assembly can switch once per second, a frequency that supports moderate cycling tasks while limiting heat rise. Thermal limits are defined by a maximum coil surface temperature of 120 °C, so cabinet ventilation must maintain acceptable ambient conditions. A concealed manual override marked N9 lets maintenance staff shift the spool without electrical power during troubleshooting. The dual-solenoid configuration weighs 1.95 kg, which eases handling during installation on compact manifolds.
