FAQs

Valve diagnostic testing is the process of evaluating the health and performance of a control valve, actuator, and associated components to identify issues before they lead to failure. Diagnostic testing helps detect problems such as excessive friction, air leaks, improper calibration, stiction, actuator degradation, and valve travel issues.

Valve diagnostics provide early warning signs of developing problems, allowing maintenance teams to address issues during scheduled outages rather than after a valve failure occurs. By identifying performance degradation before it impacts operations, facilities can reduce the risk of unexpected shutdowns and production interruptions.

Yes. Proconex offers diagnostic solutions that can evaluate control valve performance while the valve remains in operation. In-service testing allows facilities to gather valuable performance data without interrupting production, helping maintenance teams make informed decisions about repairs and maintenance planning.

Predictive valve maintenance helps organizations improve equipment reliability, reduce emergency repairs, optimize maintenance budgets, and extend valve service life. By basing maintenance decisions on actual valve condition rather than fixed schedules, facilities can focus resources where they are needed most.

The ideal testing frequency depends on the valve's criticality, service conditions, process demands, and maintenance history. Critical valves that have a significant impact on safety, environmental compliance, or production uptime may require more frequent diagnostics to ensure reliable operation.

alve diagnostics can uncover issues such as actuator wear, excessive packing friction, air supply leaks, valve stiction, calibration drift, travel deviations, and other performance problems that may affect process control and reliability. Early detection enables corrective action before a failure occurs.

Valve diagnostics provide data-driven insights into valve condition and performance trends, helping maintenance teams prioritize repairs, schedule downtime more effectively, and make informed asset management decisions. This approach bridges the gap between reactive maintenance and a fully predictive maintenance strategy.
