Use electronic solenoids to open a valve spool by variable degrees. This allows a single valve to control both the direction and the precise speed of an actuator based on an electrical input signal (e.g., 4-20mA or 0-10V). Can’t copy the link right now

But why is this specific text so revered? And what should you look for if you need a digital reference?

| Symptom | Likely Cause (Rohner’s order) | |--------|--------------------------------| | Cylinder drifts when valve centered | Worn spool / lands or pilot check leaking | | Slow actuation, full pump flow | Clogged pilot filter or low solenoid voltage | | Overheating oil | Relief valve partially open or wrong valve overlap | | Jerky motion at low speed | Stick-slip + too high dP across proportional valve |
