Rexroth 4WE10E5X/HG24N9K4/M Directional Valve - FAQ
Q1: What is the unique feature of the "E5X" spool?
A: The "E5X" spool has a unique center position function. In the neutral (spring-centered) state, it connects the pressure port (P) to both work ports (A & B) and also to the tank port (T). This creates a specific pressure condition on both sides of an actuator.
Q2: What is this center position used for?
A: This "open center to A, B, and T" configuration is less common. It is typically used in specialized applications, such as holding a double-acting cylinder under equal pressure from both sides in the neutral position, or in certain closed-center circuits that require a specific pre-charge or unloading path. It is not a standard float or closed-center function.
Q3: How is the valve operated?
A: It is controlled by a single 24V DC solenoid ("HG24N9K4" coil). Energizing the solenoid shifts the spool to one working position. De-energizing it allows internal springs to return the spool to the unique center position described above. A manual override is provided.
Q4: What are the pressure and flow ratings?
A: Maximum operating pressure: 315 bar. Maximum recommended flow rate: 60 liters per minute.
Q5: What are the electrical details?
A: The solenoid operates on 24V DC, with a protection class of IP65. Please refer to the official data sheet for exact power and current specifications.
Q6: How is the valve installed?
A: It mounts on a standard ISO 4401-05 (CETOP 5) subplate. The hydraulic ports are G 1/4". Electrical connection is via a standard plug connector.
Q7: What are the fluid requirements?
A: Use standard mineral-based hydraulic oils (HL, HLP). High fluid cleanliness (ISO 4406 20/18/15 recommended) with proper filtration is essential.
Q8: Where can I find the complete technical information?
A: For the complete datasheet, performance curves, and the exact hydraulic symbol for this specific spool type, please consult the official technical documentation for order code R901390857.
