Rohner hammers this fundamental truth. Novices think pressure is "pushed" by the pump. Rohner corrects this: pressure is a reaction to the load and the flow restriction. | Step | Action | |------|--------| | 1

This is still taught in modern servo-hydraulics courses, but Rohner’s version includes practical valve deadband compensation.
Most “spool leak” problems are actually incorrectly applied pilot logic.
