Rexroth 4WEH22E7X/6EG24N9ETK4/B10 Valve - FAQ

Q1: What is the function of the "E7X" main spool?

A:​ The "E" series spool typically has a specific center configuration. A common function is that in the neutral position, the pressure port (P) connects to the tank (T) and to both actuator ports (A & B). This unloads the pump and applies pressure to both sides of the actuator. Please verify the exact symbol in the datasheet.

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

A:​ Valves with a 22 mm nominal size are designed for high flow applications. The maximum flow rate is typically in the range of 400 to 500 liters per minute, depending on the specific spool and system pressure conditions.

Q3: How is the valve controlled?

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

Q4: What are the physical specifications?

A:​ The valve is relatively heavy, with an approximate weight of 12-15 kg. It mounts on an ISO 4401-08 (CETOP 8) subplate. The product is manufactured in the company's production facilities. Shipping is handled from regional distribution centers.

Q5: Where can I find complete technical information?

A:​ For installation dimensions, wiring diagrams, performance curves, and the definitive spool function, consult the official documentation for order code R900943534.
