The 4WE6D6X/EG24N9K72L AN directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow in automated machinery that requires reliable on-off control of pressure lines. The valve is supplied in size 6 which sets the nominal flow path dimensions. A porting pattern in accordance with ANSI B93.9 aligns the mounting face with common subplates. The solenoid operates on a nominal voltage of 24 V DC, and a voltage tolerance of ±10 % keeps actuation stable under typical supply variations. Electrical demand is limited to a nominal power of 30 W. Wiring is completed through an M12×1 four-pin connector with an integrated LED identified as K72L.
The unit withstands a maximum operating pressure of 350 bar on ports P, A, and B, while the T port is rated for 210 bar. It permits a continuous flow of up to 80 l/min in direct-current service. A duty cycle of 100 % ED (S1) lets the coil remain energized indefinitely. The coil surface may reach 120 °C before thermal limits are met. A concealed manual override labeled N9 allows local shifting without removing protective covers. Environmental sealing reaches IP65, and the construction meets protection class III for safety in low-voltage circuits. Maximum switch-off overvoltage is limited to 500 V to protect the coil insulation and upstream drivers.
