Valve Reliability in Safety Instrumented Functions
Jim Cahill
The three key components in a safety instrumented function (SIF)—sensor, logic solver and final element—each have their own probabilities of how they will perform, or not perform, when called upon to bring the process to a safe state. Of these three components, the final element is more like to fail on demand due to its role in touching the process and mechanically operating. In a Hydrocarbon Engineering article, Improving…

When is a SIL Suitability Rating Required for Final Control Elements?
Jim Cahill
Abstract Final Control Elements (Control valves or Safety Shut Down Valves) are the key components of any close loop control system, whether it is used for Basic Process Control Systems (BPCS) or for Safety Instrumented Systems (SIS). Financial constraints derive different constructions of valves suitable for throttling vs On-Off applications. However, due to past accidents, reliability has become a key criterion in…
