Rexroth 4WE10D5X/EG220N9K4/M Directional Valve - FAQ

Q1: What is the primary function of this valve?

A:​ It is an electrically operated directional valve used to control the start, stop, and direction of hydraulic fluid flow, typically to command the movement of cylinders or motors in an industrial hydraulic system.

Q2: How is this valve different from other 4WE10 models?

A:​ The main distinction is its operating voltage. The "EG220N9K4" designation specifies a solenoid coil designed for 220V AC, 50Hz​ power supply. Other models may use 24V DC, 110V AC, or other voltages.

Q3: What does the "D5X" spool do?

A:​ The "D5X" spool has a "closed center" function. In its neutral (spring-centered) position, it blocks all four connections: the pressure port (P), the two work ports (A, B), and the tank port (T). This locks the actuator in place.

Q4: How is the valve controlled?

A:​ It is controlled by a single 220V AC solenoid. When the solenoid is energized, it shifts the spool. When de-energized, internal springs return the spool to the closed-center neutral position. A manual override is provided for testing.

Q5: What are the key pressure and flow ratings?

A:​ The maximum operating pressure is 315 bar. The maximum recommended flow rate is 60 liters per minute.

Q6: What are the electrical specifications?

A:​ The standard coil operates on 220V AC, 50Hz. The coil has a protection class of IP65. Always verify the exact power consumption, inrush current, and frequency tolerance (e.g., 50/60Hz) from the official data sheet.

Q7: How is it mounted and connected?

A:​ It uses a subplate mounted according to the ISO 4401-05 (CETOP 5) standard. Hydraulic ports are G 1/4". The electrical connection is made via a plug connector (DIN 43650 Form A).

Q8: What are the fluid and maintenance requirements?

A:​ Use standard mineral-based hydraulic oils (HL, HLP). Maintain high fluid cleanliness (ISO 4406 20/18/15 is recommended) with proper filtration to ensure reliability and long service life.

Q9: Where can I find complete wiring and installation details?

A:​ For complete electrical data, wiring diagrams, performance curves, and installation instructions, please consult the official technical documentation for the specific order code R901339383.
