Rexroth 4WEH22J7X/6EG24N9ETK4/B10 Valve - FAQ

Q1: What is the center function of the "J7X" spool?

A:​ The "J7X" spool designation typically indicates a "tandem" or "float" center function. In the neutral (centered) position, the pressure port (P) is blocked, and both actuator ports (A and B) are connected to the tank (T), allowing the connected cylinder or motor to move freely.

Q2: What is the flow capacity of this 22 mm valve?

A:​ As a high-flow valve with a 22 mm nominal size, its typical maximum flow rate is in the range of 400 to 500 liters per minute. The exact value depends on operating pressure and the specific configuration.

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 input. This pilot stage uses hydraulic pressure to shift the large main spool, enabling precise control of high flow rates with a standard electrical signal.

Q4: What are the key material and physical specifications?

A:​ The main valve body is constructed from aluminum alloy. The valve is relatively heavy, with an approximate weight of 12-15 kg. It is designed to mount on a standard ISO 4401-08 (CETOP 8) subplate.

Q5: Where can I find complete installation and performance details?

A:​ For complete technical specifications, including dimensional drawings, wiring diagrams, detailed performance curves, and the definitive hydraulic symbol for the J7X spool, please consult the official product documentation for order code R900932049.
