The 4WE6GB6X/EG24N9K72L/62 valve is part of the WE Directional Spool Valves series from Bosch Rexroth and is intended to shift hydraulic flow paths in automated machinery. The size 6 (NG6) envelope fits compact manifolds, while the NFPA T3.5.1 D03 mounting interface lets it bolt directly to common subplates. A porting pattern of ISO 4401-03-02-0-05 guarantees interchangeability with other components that share this footprint. Four main ports route pressure, return, and two actuator lines through the body. The valve handles up to 350 bar on P, A, and B ports, supporting high-pressure work circuits. Its solenoid operates at 24 V DC and tolerates a ±10 % supply variation, so control panels need no tight regulation. Coil power is limited to 30 W to curb heat build-up, and a 100 % ED duty cycle allows continuous energization without thermal overload.
An M12 four-pin connector identified as K72 provides quick electrical hookup, and when mated it upgrades the enclosure to IP65 for resistance to dust and water spray. Flow capacity reaches 60 l/min when driven by an AC supply and rises to 80 l/min under DC operation, enabling rapid cylinder movement in either case. The tank port can sustain 210 bar in DC service, allowing back-pressure where needed. A maximum switching frequency of 4.2 cycles per second supports moderate on-off modulation in repetitive sequences. Total weight is 1.95 kg, so the valve can be installed or replaced by one technician without lifting gear.
