Independent audit findings show that as much as 40% of process variability is caused by control valves. The effects of high variability can result in increased raw material costs, higher than expected energy usage, lower output, reduced operating equipment effectiveness and product quality issues. Emerson has been performing extensive dynamic performance testing on control valves since early 1990s that led to valve design that enable optimum performance.
Watch a video demonstration that shows how control valve performance impacts loop variability.
Are there opportunities to reduce process variability in your plant?
