The 4WE6D73-6X/EG24N9K72L/A12/62 AN directional spool valve is produced by Bosch Rexroth and belongs to the WE Directional Spool Valves series. The valve controls the direction of hydraulic oil and is sized as nominal size 6 to fit standard CETOP 3 interfaces. Its porting pattern follows ANSI B93.9 (AN), allowing interchangeability with North American manifold blocks. The pressure ports p, a, and b endure up to 350 bar so the unit can handle high-pressure circuits in industrial presses and machine tools. A maximum flow of 80 l/min supports medium throughput without exceeding permissible pressure drops. System cleanliness must meet ISO 4406 class 20/18/15 to prevent spool sticking and premature wear. An IP65 enclosure protects the solenoid housing against dust ingress and low-pressure water jets, while the M12x1 four-pin electrical connector with coding A provides a sealed interface for control wiring.
The solenoid operates from a nominal voltage of 24 V DC and draws a rated current of 1.25 A, enabling direct connection to common PLC outputs. Nominal power consumption is 30 W, so panel designers can size power supplies and thermal management accordingly. A voltage tolerance of ±10% allows stable switching even with modest supply variation. Continuous duty operation is possible because the coil is specified for a 100% ED duty cycle, ensuring it remains energized without overheating. A concealed manual override identified as N9 lets maintenance personnel shift the spool during commissioning or fault finding without exposing the mechanism to contaminants. The locating hole uses an ISO 8752-3x8-St spring pin to align the valve accurately on subplates. Tank port dc is limited to 210 bar, guiding designers to select return-line components that match this restriction.
