Rexroth H-4WEH25J6X/6EG24N9ETK4/B10D3 Valve - Key Parameters

Rexroth H-4WEH25J6X/6EG24N9ETK4/B10D3 Valve - FAQ

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

A:​ This valve is designed for very high flow hydraulic systems. It is typically used in large industrial machinery, heavy-duty presses, and other high-power applications where controlling hydraulic cylinders or motors with flow rates of 600-800 liters per minute or more is required.

Q2: What is the center function of the "J6X" spool?

A:​ The "J6X" designation typically indicates a "tandem center" or "float center" function. In the neutral position, the pressure port (P) is blocked, and both actuator ports (A and B) are connected to the tank (T). This allows the connected actuator to move freely if an external force is applied.

Q3: How is the valve controlled?

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

Q4: What are the key physical and installation specifications?

A:​ The valve is heavy, with an approximate weight of 20-25 kg. The main body is typically made of aluminum alloy or ductile iron. It mounts on a large ISO 4401-10 (CETOP 10) subplate. The product is manufactured in accordance with industry standards.

Q5: What does the "B10D3" suffix indicate?

A:​ This suffix is a specific variant code that indicates detailed engineering options related to the valve's performance characteristics, such as its spring centering force, spool overlap, or other control parameters that define its precise operational behavior.

Q6: Where can I find complete technical data?

A:​ For complete installation dimensions, wiring diagrams, performance curves, and definitive specifications, please consult the official product documentation for order code R900932940.
