Development Of A Controller For Partial Stroke Testing: Metso Neles

Partial Stroke Valve Testing (PST) which is related to the Emergency Valve Shutdown System is a method whereby the performance of a portion of a valve is tested at more frequent interval (accelerated proof test). PST can be a good complement to Full Stroke Testing (FST). The objective of this project is to develop a control for a PST that is based on a system called Programmable Logic Controller
(PLC) as the main controller to do Full Stroke Testing and for the Partial Stroke Testing: it was conducted using software provide by the vendors. The problems that have been identified during the system familiarization and training session are needed to be solved in order to meet the project's objective.
