An Experimental Study on the Response Characteristics of Current-Pneumatic Control Valve

전류-공기압 컨트롤 밸브의 응답특성에 대한 실험적 고찰

  • Published : 2001.02.01

Abstract

The positioner is an essential component of the control valve which is used to control quantity of the liquid in the pipe of chemical plants. In this paper, the experimental methodology for current pneumatic positioner was developed for the investigation of the static and dynamic characteristics of the positioner. The methodology was applied to evaluate response characteristics of two different positioners, which are current model in market and newly designed model. The experimental results of these two models were compared and analyzed.
