A1: The 4WE6 series is widely used in low-to-medium flow hydraulic systems (≤80 L/min) across industries such as:

• Industrial machinery: Injection molding machines (controlling mold opening/closing), press machines (regulating ram lifting/lowering), and conveyor systems (adjusting belt tension).
• Mobile equipment: Small excavators (controlling arm and bucket movement), forklifts (managing fork lifting/lowering), and agricultural machinery (operating plows or seeders).
• Automation systems: Hydraulic clamps (controlling clamping/releasing actions) and robotic arms (adjusting joint movement).

A2: Follow these 4 steps for accurate selection:

1. Determine spool function: Choose based on the actuator's required neutral state (e.g., "D" function: P blocked, A/B connected to T - suitable for cylinders that need free retraction; "Y" function: P/A/B blocked, T open - ideal for cylinders requiring position holding).
2. Match pressure/flow: Ensure the valve's rated pressure (315 bar) and maximum flow (up to 80 L/min) exceed the system's actual operating pressure and flow (e.g., for a system with 250 bar pressure and 60 L/min flow, the 4WE6 is fully compatible).
3. Select solenoid voltage: Align with the system's power supply (DC 24V for mobile/industrial equipment; AC 220V for fixed equipment connected to the grid).
4. Choose mounting/auxiliary features: Opt for manifold-mounted (J-suffix) valves for compact systems, threaded-port (M-suffix) valves for direct pipeline connection, and valves with manual emergency operation (K4-suffix) for critical applications requiring backup control.
