Abstract
The aim of the present work was to develop a low-cost valve built from a servomotor and an ordinary commercial valve, made of cast iron. A structure built by a 3-D printer, using a thermoplastic material - ABS (Acrylonitrile Butadiene Styrene) was developed in order to mechanically connect the valve to the servomotor. An FEA (Finite Element Analysis) was carried out in order to optimize the printed structure. A PIC 12F675P - 8-bit microcontroller - was employed to control the servomotor axle position and to allow the communication of the valve with a PLC (Programmable Logical Controller). The valve was tested in a reduced scale plant that represents a continuous industrial process with communicating vessels where a PID (Proportional-Integral-Derivative) control technique was applied.
