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.
The paper presents a hydraulic volumetric speedcontrol system based on converter technique, laying stress on the introduction of the structure and working principles of the system.
The article analyses two throttle speed regulation hydraulic system and presents the control method to in line throttle speed regulation hydraulic system.
