Do you know the true condition of your control valve installed base?
Unplanned maintenance activities and premature valve replacements represent significant financial and operational challenges. Studies indicate that only 30% of control valves are genuinely defective or underperforming, yet they are responsible for more than half of the associated maintenance expenditures.
