Final control elements are very important equipments in an industrial control plant. These devices are responsible for acting on the manipulated variables of a process, trying to keep some other parameter inside a desirable range. Among all the final control elements,it is right to say that valves are the most employed tools in industry – a fact which explains the study and comprehension of these dispositives. Even though, there are many cases where the choice of the best valves for an industrial unit is yet neglected, once there is several variables that can influence these devices’ projects – such as the physical state and composition of the downstream fluid, flow rate, temperature, pressure and so on – and also a great variety of valves available on the market. That said, the object of this paper is the development of a software that represents, in a simple way, the required steps to choose a proper valve for operations with liquid fluids. The program’s main function is to show the principal measures for a correct selection of a final control element, so the equipment can garantee a good procedure, without unexpected problems or physical state changement scenarios
