Valve description
Operating principle of Pre-Compensated Load Sensing technology
The main feature of this principle is that the flow rate to the user is proportional to the spool position under any operating
condition, regardless of the resistance encountered by the user (pressure) and the number of activated levers (exceeding the
pump’s total flow rate, a condition hereinafter defined as saturation, is the only limitation).
