Rexroth 4WEH10J4X/6EG24N9ETK4/B10 Valve - FAQ

Q1: How is the 4WEH10 valve different from a standard 4WE10?

A:​ The 4WEH10 is a two-stage, pilot-operated valve. A small, low-power solenoid pilot valve controls a larger hydraulic main stage, allowing it to handle much higher flow rates (typically 100+ l/min) with a standard 24V DC signal. A standard 4WE10 is directly solenoid-operated for lower flows (~60 l/min).

Q2: What is the function of the "J4X" main spool?

A:​ The "J4X" designation refers to the main spool's center position function. In the J-type configuration, the spool typically blocks the pressure port (P) and connects both actuator ports (A & B) to the tank (T) in the neutral position, providing a "tandem" or "float" center. The exact hydraulic symbol should be verified in the datasheet.

Q3: How is the valve operated?

A:​ It is controlled by a double-solenoid pilot valve ("6EG24N9ETK4"). Energizing one of the 24V DC solenoids on the pilot valve shifts the main spool. De-energizing both allows springs to return the main spool to its J4X center position. The "/B10" suffix often relates to the spring centering characteristic.

Q4: What are the key operating limits?

A:​ Maximum operating pressure for the main stage is typically 315 bar. Maximum flow capacity is much higher than direct-acting valves, often 100 l/min or more. The nominal size is 10 mm.

Q5: Where can I find complete specifications?

A:​ For the complete datasheet, including the exact J4X center function, flow-pressure curves, pilot pressure requirements, and electrical data, consult the official documentation for order code R900948924.
