4WE6E6X/EG220N9K4/V/62

The 4WE6E6X/EG220N9K4/V/62 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. Designed for hydraulic automation, it switches flow paths in compact manifolds and actuator lines. It uses valve size 6 to fit ISO subplates while maintaining moderate flow capability. The internal spool follows symbol E, providing two directional positions for cylinder control. The assembly withstands system pressures up to 350 bar at ports A, B, and P so it can operate in high-pressure circuits, and it tolerates 210 bar on the tank port to protect return plumbing. A maximum direct-current flow of 80 l/min defines the throughput permitted without excessive pressure drop. Mounting is simplified by the ISO 4401-03-02-0-05 porting pattern, ensuring interchangeability with standard CETOP 03 subplates. FKM seals resist mineral oil and many synthetic fluids for long service life. A concealed N9 manual override allows manual shifting during commissioning, and an ISO 8752-3x8-St locking pin holds the tube assembly in place under vibration.

The solenoid section operates from a nominal 220 V DC supply, and the coil accepts a ±10 % voltage variation to accommodate industrial power fluctuations. Under nominal conditions it draws 0.14 A, resulting in an electrical load of 30 W that minimizes heat generation in enclosed cabinets. Continuous energization is permitted because the duty cycle is rated at 100 % ED, eliminating the need for cool-down intervals during repetitive machine cycles. The K4 connector in accordance with DIN EN 175301-803 provides a standardized plug-in interface for quick wiring. An IP65 enclosure rating keeps dust tight and shields against low-pressure water jets, supporting installation on mobile equipment or exposed plant machinery. This rating also prevents ingress of hydraulic oil mist that frequently builds up around power units, preserving coil insulation. Full duty capability means the armature can remain magnetized for the entire machine cycle without exceeding allowable winding temperature. The low input current simplifies selection of relay contacts and reduces power supply sizing in distributed I/O panels.
