The 3WE10A3X/CG24N9K4/B20 valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series and is used to shift flow paths in hydraulic automation systems. The unit provides a 3/2-way function so it can alternate one service line between pressure and tank. Its nominal size of 10 (NG10) matches medium-capacity manifolds. The body follows the NFPA D05 mounting interface, and port locations conform to ISO 4401-05-04-0-05 for standardized subplate installation. Actuation is handled by a wet-pin high-power solenoid energized at 24 V DC for reliable force generation. The coil carries Class H insulation, allowing a permissible surface temperature of 180 °C during continuous duty. An IP65 enclosure rating protects internal components from dust and low-pressure water jets.
The hydraulic flow path supports up to 120 L/min, making the valve suitable for presses, molding machines, and similar equipment. A maximum operating pressure of 315 bar accommodates high-pressure supply lines without derating. Spool shifts can be commanded at rates up to 7200 cycles per hour, enabling rapid repetitive sequencing. Electrical hookup is provided through a DIN EN 175301-803 K4 connector, which permits quick coil replacement in the field. A concealed manual override (N9) allows technicians to move the spool mechanically during commissioning or power loss. After each command is removed, a spring return forces the spool to its rest position for safe circuit neutralization. NBR seals maintain oil tightness and resist common hydraulic fluids across the stated pressure and temperature ranges.
