Rexroth H-4WEH25E6X/6HG24N9ETK4/B10D3 Valve - FAQ

Q1: What is the main application for a 25 mm valve like this?

A:​ This valve is designed for very high flow industrial hydraulic systems. It is typically used to control large cylinders or high-power hydraulic motors in applications such as large presses, heavy machinery, and industrial automation where flow rates can exceed 600 liters per minute.

Q2: What is the likely function of the "E6X" spool?

A:​ The "E" series designation often indicates a specific pressure-center configuration. A common function for larger valves is that in the neutral position, the pressure port (P) is connected to the tank (T) and also to both actuator ports (A & B), which unloads the pump and applies system pressure to both sides of the actuator. Please verify the exact symbol in the datasheet.

Q3: How is this high-flow valve controlled?

A:​ It uses a two-stage, pilot-operated design. A compact double-solenoid pilot valve (24V DC) provides the electrical control signal. This pilot valve directs hydraulic fluid to shift the large main spool, allowing precise control of very high flow rates with standard electrical components.

Q4: What are the key specifications for installation?

A:​ The valve has a nominal size of 25 mm and requires a large mounting interface, typically an ISO 4401-10 (CETOP 10) subplate. It is a heavy component, with an approximate weight of 20-25 kg. The main body is typically constructed from aluminum alloy or ductile iron.

Q5: What does the "B10D3" suffix mean?

A:​ This suffix is a specific variant code that indicates detailed engineering options, such as spring centering characteristics, spool overlap (metering), or other control performance specifications. It defines the precise operational behavior of the valve.

Q6: Where can I find complete technical details?

A:​ For installation dimensions, wiring diagrams, performance curves, and the definitive specifications for the E6X spool, please consult the official product documentation for order code R901119654.
