Abstract—Control valves are essential components in process control industry. They are the final control elements that play an important role to regulate flow rate. The condition of control valves affect the whole cycle of process. Therefore, information about their health would be useful to plant personnel during maintenance. This project proposes acoustic emission (AE) technique for control valve fault detection. This paper discusses two methods used for data collection. Data acquisition system (DAQ) was used for retrieving data in time domain while spectrum analyzer was used for frequency domain data.
