4WE6D9-6X/EG96N9K4/N15/62

The 4WE6D9-6X/EG96N9K4/N15/62 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow for automation circuits by shifting a solenoid-actuated spool. The solenoid operates at a nominal 96 V DC, so control cabinets can use a dedicated low-voltage supply. A rated current of 0.33 A establishes the magnetizing force required to move the spool under full pressure. The coil consumes 30 W, which defines heat generation and power budgeting in the control system. Continuous energization is permitted because the coil is specified for a 100 % duty cycle, ensuring the spool can remain in position without thermal derating. The voltage tolerance of ±10 % allows reliable actuation despite supply variation. Electrical connection is made through a DIN EN 175301-803 plug, simplifying wiring with standardized field connectors. A concealed N9 manual override lets maintenance personnel shift the spool during commissioning or power loss without exposing moving parts. The valve can switch up to 4.2 cycles per second, supporting rapid cycling in machine sequences.

Hydraulic performance reaches a maximum flow of 80 l/min, allowing the valve to serve medium-size actuators without excessive pressure drop. It withstands operating pressures up to 350 bar on pressure ports, fitting high-pressure circuits common in presses and injection machines. The tank port may see up to 210 bar, so return lines can carry elevated back-pressure without risking leakage. An IP65 enclosure prevents dust ingress and water jets from affecting the solenoid or internal wiring. Mounting uses the ISO 4401-03-02-0-05 porting pattern, enabling direct stacking on subplates that share this interface. NBR seals are fitted to resist conventional mineral oil fluids at standard temperature ranges. A locating hole with a 3×8 mm ISO 8752 spring pin ensures repeatable positioning on the manifold. Throttle inserts of 1.5 mm in ports A and B provide basic flow metering to dampen actuator motion and reduce shock loads.
