The Importance of Valve Maintenance in Industrial Plants
Why Valve Maintenance Matters
Valves are among the most critical components in any industrial piping system. A single valve failure can lead to unplanned shutdowns, environmental hazards, and safety incidents costing millions. Proactive maintenance extends valve life, reduces total cost of ownership, and ensures regulatory compliance.
Common Causes of Valve Failure
- Corrosion and erosion from aggressive media or high-velocity flow
- Seat and seal degradation due to thermal cycling or chemical attack
- Stem packing leakage from wear or improper torque
- Actuator malfunction caused by moisture ingress or lack of lubrication
Recommended Maintenance Practices
Visual Inspection
Regular walk-down inspections should check for external leaks, corrosion, damaged handwheels, and missing nameplates. BDK recommends quarterly visual checks for critical service valves.
Functional Testing
Stroke-testing isolation valves during planned turnarounds verifies they can fully open and close. Partial stroke testing (PST) of emergency shutdown valves can be done online without process disruption.
Predictive Maintenance
Advanced techniques such as acoustic emission monitoring, valve signature analysis, and thermal imaging help detect internal leakage and seat wear before failure occurs.
