Rexroth 4WE10Y5X/HG24N9K4/M Directional Valve - Key Parameters

Rexroth 4WE10Y5X/HG24N9K4/M Valve - FAQ

Q1: What is the center position function of the Y5X spool?

A:​ In the neutral (center) position, the Y5X spool blocks the pressure port (P) and work port A, while connecting work port B directly to the tank (T).

Q2: What is this center position used for?

A:​ This is a specialized configuration. It is typically used in circuits where one side of a double-acting actuator (connected to port B) must be free to drain or retract under an external force when the valve is centered, while the other side (port A) and the pump are locked. It can be used for specific clamping, sequencing, or safety functions.

Q3: How is the valve controlled?

A:​ It is operated by a 24V DC solenoid. Energizing the solenoid shifts the spool to a working position. De-energizing it allows a spring to return the spool to the Y5X center position. A manual override is included.

Q4: What are the main operating limits?

A:​ Maximum pressure: 315 bar. Maximum flow: 60 l/min. It uses standard ISO 4401-05 (CETOP 5) mounting.

Q5: Where can I find the complete technical data?

A:​ For the full datasheet, performance curves, and the official hydraulic symbol, refer to the technical documentation for the specific order code R901391202.
