A plant can have thousands of valves, and the few that hurt most are rarely the ones getting attention. A relief valve test slips past its due date, a leaking isolation valve gets noted on a walkdown and never becomes a job, and the repair history lives in a spreadsheet and in one technician's memory. Valve reliability is mostly a record-keeping and prioritization problem. OxMaint AI gives every valve its own asset record, inspection history, test schedule and work orders in one maintenance platform.
Power Plant Valve Maintenance: Inspection, Testing & Reliability Guide
Rank the valves that matter, inspect them on a schedule, test the safety-critical ones on time, and learn from every failure. OxMaint AI connects that loop in one platform: inspections raise defects, defects become work orders, and test and repair history drives preventive and predictive maintenance.
Automated test scheduling and better visibility of every valve's history.
Step One: Rank Valves by Criticality
You can't give every valve the same attention, and you shouldn't. Rank by what happens if it fails: safety, generation loss, environmental impact and repair lead time. Then spend effort in that order. Start free and tag each valve with a criticality class.
Four Valve Families, Four Different Plans
Valves are not interchangeable, so one PM template won't fit. Match the check to how each family fails. Book a demo to see per-type templates.
An Inspection Calendar by Cadence
Frequencies are set by the manufacturer, your applicable code and jurisdiction, and your own failure history. What matters is that each layer exists and is tracked. Start free and schedule each layer.
Give Every Valve a Record, Not Just the Ones That Failed.
The overdue test and the repeat repair are both visible the moment each valve has a tag, a criticality, a schedule and a history. OxMaint AI keeps all four together and alerts you before a test date passes.
Failure Analysis: Read the Warning Signs
Most valve failures announce themselves. The job is catching the sign early and turning it into a work order. Book a demo to see issue-to-work-order action.
| Failure mode | Early sign | Typical action |
|---|---|---|
| Seat leakage | Downstream temperature or pressure drift, audible passing | Schedule lapping or seat repair |
| Packing / gland leak | Visible weeping, stem corrosion | Adjust or repack at next window |
| Sticking / slow stroke | Longer stroke time, hunting on control loop | Check actuator, positioner, stem |
| Set-point drift (relief) | Test result outside tolerance | Reset, repair, review test interval |
| Erosion / wear | Rising vibration or noise, repeat repairs | Compare repair cost with replacement |
Track repeat repairs per valve. Looking at the total cost of repeated fixes next to the valve's criticality gives a clearer repair-or-replace answer than judging each job alone. Start free and see cost per valve.
What Every Valve Record Should Hold
Start with a physical walkdown of the highest-criticality systems, capture tags, types and locations, then fill specifications from as-built drawings. Spreadsheet imports let you create valve assets in bulk. Start free and import your list.

Frequently Asked Questions
Know Every Valve. Prove Every Test.
Valve reliability comes from a rank, a schedule and a record for each valve. Put them in one platform where inspections raise defects, defects become work orders, and test dates never slip by.
