4WE6J6X/EG12NDA/V/62

The 4WE6J6X/EG12NDA/V/62 directional spool valve is produced by Bosch Rexroth and belongs to the WE Directional Spool Valves series. It directs hydraulic flow in automated circuits for machine tools, presses, and mobile systems. The clamping length is 42 mm, defining the space needed for secure mounting on a sub-plate. A continuous duty cycle of 100 % ED allows the solenoid to stay energized without thermal pauses, supporting nonstop control sequences. With a maximum switching frequency of 4.2 cycles per second in direct-current service, the unit can modulate flow rapidly during proportional tasks. The valve passes up to 80 l/min in direct-current operation, permitting medium-capacity actuators to move at their designed speeds. Electrical actuation relies on a 12 V DC supply; at this nominal voltage the coil draws a rated current of 2.5 A and consumes 30 W, providing the magnetic force needed to shift the spool. A voltage tolerance of ±10 % ensures reliable function when the onboard supply fluctuates within typical vehicle or plant limits.

Clean hydraulic media prolongs service life, so the valve is specified for contamination level 20/18/15 per ISO 4406; circuits must filter oil accordingly. When the solenoid is de-energized, the winding can generate up to 500 V of switch-off overvoltage, a value that guides the selection of surge suppressors. The pressure chambers a, b, and p withstand up to 350 bar, allowing the component to control high-pressure work lines, while the tank port is rated for 210 bar to suit return circuits. Interface compatibility is provided by the ISO 4401-03-02-0-05 porting pattern, enabling direct installation on standardized NG6 manifolds. An FKM seal set resists mineral oils and many synthetic fluids, supporting elevated temperatures common in continuous cycles. With two solenoids installed the assembly weighs 1.95 kg, light enough for compact stacking on modular plates yet substantial enough to dampen vibration. These characteristics confirm its suitability for precise, high-duty hydraulic automation without introducing unlisted attributes.
