There are many industrial applications where precise delivery of fluid required such as ratio blending, delivery system, etc. One of such application is petroleum product delivery system. As the price of these petroleum products is increasing day by day, it is important to deliver the exact demanded quantity of product to the customer. For such delivery systems the digital control valve is used. This paper deals with the simulation of the digital control valve. The motivation behind this is, if we know the behavior of the digital control valve then we can develop different control strategies so that the fluid delivery can be done with accuracy and precision.
