Electric Final Control Devices

Recording Date: June 2017

While majority of safety instrumented functions utilize a valve assembly as the final element a fair number use electric final elements. There is less data and experience available for electric final elements making the design and maintenance areas of the lifecycle more challenging. This webinar will review some of the more common electric final elements, the data available for modeling them, and some of the considerations to include when designing them into safety systems.
