In this paper, it firstly has expounded the disadvantage of conventional positioner and then introduced the principle and appttcation of intelligent valve positioner in chemical engineering production, finally introduced the problems of intelligent valve positioner in chemical engineering production and the resolution. In the process of chemical engineering production, utilizing the intelligent valve positioner can improve the accuracy and stability of control so that to guarantee its extensive application. On the other hand, the intelligent valve positioner has the independent module base, besides, it can take recombination through switching the module and adopting the two-wire system to input and output signal and improve its safety. With the development of modern science and technology and the increase of chemical engineering, the intelligent valve positioner will have a good development prospect.
