Solenoid operated valves are vital components in many process control systems. They are components that are often critical to safety. Solenoid valve degradation is difficult to detect in situ, leading to failures, which are often sudden and unexpected. This paper reviews some of the common causes of solenoid valve degradation and discusses strategies that leverage these mechanisms to detect and diagnose faults before they lead to failure.
