A useful maintenance plan is based on duty severity and observed condition. A universal calendar interval is less informative than a record of how the specific valve behaves in its process.
Create a baseline
At commissioning, retain the approved datasheet, stroke settings, normal operating travel and expected response. Record available positioner diagnostics and the condition of air preparation. This baseline makes later changes in friction, travel time or leakage easier to interpret.
Trend the indicators that matter
Track control stability, travel response, external leakage, air consumption and any change in actuator behavior. Inspect accessible mounting and utility components through approved procedures. A gradual increase in required force or repeated failure to reach position may justify planned inspection before the next outage.
Define the maintenance boundary
Specify who can inspect, adjust or disassemble the assembly and what isolation is required. Use the supplied instructions for the exact valve and actuator. After work that can change sealing or travel, perform the appropriate functional and leakage verification. Keep the record linked to the tag and update the spare-parts plan from actual findings.
Practical checklist
- Commissioning baseline retained.
- Condition indicators and review frequency defined.
- Authorized procedures and isolation requirements clear.
- Repair findings and retest results recorded.
