The 4WE6H6X/EG24N9K72L/62 directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and is used to route pressurized oil to hydraulic actuators. It follows the ISO 4401-03-02-0-05 porting pattern and fits the NFPA D03 manifold layout, so it bolts directly onto standard subplates. The valve manages 350 bar at ports P, A, and B, while the T return port is limited to 210 bar during direct-current operation. A maximum flow of 80 l/min supports medium-size cylinders and motors without excessive pressure loss. The solenoid operates at a nominal 24 V DC, draws 1.25 A, and consumes 30 W during steady energization. Pin 4 of the control plug carries the same 24 V DC supply, allowing consistent wiring polarity. A 100 % S1 duty cycle lets the coil stay energized continuously for positioning or clamping tasks without overheating.
An M12×1 four-pole electrical connector provides the interface for power and control signals and enables quick disconnection during maintenance. The housing is rated IP65, so dust and low-pressure water jets cannot reach internal components in typical factory environments. A concealed manual override, identified by code N9, allows technicians to shift the spool mechanically when electrical power is absent. Once the coil is de-energized, an internal spring return forces the spool back to its neutral position to re-establish tank relief flow. System oil must meet ISO 4406 class 20/18/15 cleanliness to protect the precise spool lands and seals. A locating pin sized ISO 8752-3×8-St secures the valve body against movement on the manifold, maintaining alignment during pressure shocks.
