Abstract:
     The digital cone valve is used for the control and adjustment of fluid pressure. On the base of open-looped digital cone valve, a pressure sensor is increased and sectional linear control algorithm is utilized so as to form close-loop control. That can greatly increase the dynamic response speed and obviously improve static differential pressure, linear error, hysteresis error and other static performance. Other types of cone valves may be reformed with a cost near to that of a proportional valve. The present invention may be used for various conditions of different pressure and flow rate.
