The 4WE6E73-6X/EG24N9K4/A12 directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for routing hydraulic flow in automated machinery. Nominal size 6 (NG6) defines mounting dimensions that fit compact ISO subplates, while the ISO 4401-03-02-0-05 porting pattern ensures interface compatibility with common manifolds. A maximum flow of 80 l/min limits pressure drop at rated conditions, and the valve endures 350 bar on ports p, a, and b to support high-pressure circuits; the return port t is limited to 210 bar to protect tank plumbing. Continuous duty cycle of 100 % ED allows the coil to remain energized without cooling intervals. Electrical control is supplied at 24 V DC, the solenoid draws a rated current of 1.25 A, and operation remains stable within a ±10 % voltage tolerance.
The solenoid’s nominal power consumption is 30 W, and resulting heat raises coil surface temperature up to 120 °C, so adjacent components must withstand that level. A 3-pole connector built to DIN EN 175301-803 provides a quick, keyed electrical interface. The housing achieves an IP65 degree of protection when the connector is fitted, blocking dust and water jets for outdoor or wash-down use. A concealed manual override permits manual shifting during setup yet prevents accidental actuation in service. The design supports a maximum switching frequency of 4.2 cycles per second under direct current, sustaining rapid directional changes in high-speed hydraulic equipment. These electrical and mechanical features complement the flow and pressure capabilities outlined earlier to deliver reliable valve performance in industrial motion control.
