Rexroth 4WEH22J7X/6HG24N9ETK4/B10 Valve - FAQ

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

A:​ The "J" series 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 & B) are connected to the tank (T), allowing the connected hydraulic cylinder or motor to move freely.

Q2: What is the flow capacity of this valve?

A:​ With a 22 mm nominal size, this valve is designed for high flow applications. The typical maximum flow rate is in the range of 400 to 500 liters per minute, depending on the specific operating conditions and pressure drop.

Q3: How is the valve controlled?

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

Q4: What are the physical and material specifications?

A:​ The valve is relatively heavy, with an approximate weight of 12-15 kg. The main body is typically made of aluminum alloy. It mounts on a large ISO 4401-08 (CETOP 8) subplate.

Q5: Where can I find the complete technical data?

A:​ For installation dimensions, wiring diagrams, performance curves, and the definitive specifications for the J7X spool, please consult the official product documentation for order code R901108960.
