Insertion Losses
These curves show the typical pressure drop for each flow
path in the valve. The "P" port pressure drop is the pressure
drop for flow across the sequence valve spool in the fully
open position.
The total insertion loss for the valve must be calculated by
summing the losses through each of the four flow paths.
