Moreover, in some cases a pilot might wish to do the opposite and promote turbulent flow-for example, when slowing down.
此外，相反，在某些情况下飞行员更愿意产生紊流——例如，减速时。

It has the higher switching speed and frequency and can be used as the pilot valve for a larger flow rate valve, or as a direct control valve for small flow rate hydraulic loop.
A model were deduced, in detail, about servo pilot system according to the definition of load flow and load pressure were analyzed using simulink technology in theoretic.
