Design and Implementation of an Electric Actuated Valve for Precise Fluid Control

Abstract

Fluid control is one of the essential automation application area in industry. In order to fluid control effectively and precisely, valves which are crucial components, need a controlled rotating motion which leads to implement electric motors, electronic controller and gear systems altogether. In this study, an electric motor actuated valve system is designed and prototyped. The design phases are including switch mode power supply (SMPS) design, motor controller circuit design, mechanical implementation and controller design. The designed valve system is manufactured and tested using multi-disciplinary fashion. The application problems are solved by using the proper control techniques and strategies. The precise position control of butterfly disc is also achieved. According to the related industrial standard and application requirements, the experimental results show the effectiveness of the design approach.
