4WE6J6X/EG12N9K4/B10V

The 4WE6J6X/EG12N9K4/B10V directional spool valve belongs to the WE Directional Spool Valves series produced by Bosch Rexroth for controlling flow paths in hydraulic automation. A valve size of 6 sets the envelope dimensions so the unit fits NG6 subplates without adapters. The ISO 4401-03-02-0-05 porting pattern matches standard manifolds, allowing quick replacement in existing circuits. A J spool symbol defines the internal land geometry that switches supply, actuator, and tank lines as required by machine cycles. The B10 throttle insert with a 1.0 mm orifice in port P limits inlet surge to protect downstream components. A K4 connector following DIN EN 175301-803 provides a plug-in electrical interface that simplifies coil wiring. The coil is rated for 12 V DC to suit mobile or battery-powered installations, and it draws 2.5 A so power supplies can be sized accurately. Nominal power of 30 W indicates continuous electrical load, while a ±10 % voltage tolerance keeps actuation force within range during supply fluctuations.

A 100 % ED duty cycle permits the solenoid to remain energized continuously without thermal derating, supporting long holding periods common in automated presses or clamps. The concealed N9 manual override enables emergency shifting without exposing the mechanism to contaminants. Maximum operating pressure of 350 bar at ports a, b, and p allows the valve to work in high-pressure circuits such as injection molding or forging presses. A maximum flow of 80 l/min (direct current operation) defines the throughput the spool can pass while maintaining acceptable pressure drop. Tank port pressure is limited to 210 bar, ensuring safe return-line operation when backpressure is present. A maximum switching frequency of 4.2 cycles per second governs how rapidly the spool can alternate positions in high-speed sequencing tasks. FKM seal material resists heat and aggressive hydraulic fluids, extending service life in demanding environments.
