The useful spare-parts list depends on the selected valve, actuator and process risk. Ordering generic seals by nominal size can create compatibility and fitting problems.
Use the exact identification
Record series, size, pressure rating, seat construction, materials and valve serial or tag information. Actuator and positioner identification should be retained separately. Two valves of the same DN may use different seats, shafts or packing depending on revision and service.
Prioritize by failure and downtime risk
A project may need packing and seal kits, a matched seat/segment set, bearings, actuator seal kits or selected accessory spares. The right stock level depends on how critical the line is and how quickly replacements can be obtained. A low-value component with a long lead time can dominate outage duration.
Preserve materials and instructions
Elastomers and polymers may need specific storage conditions and have shelf-life considerations. Keep spares labelled and protected, with the corresponding assembly instructions. When a process material is changed, review compatibility of both installed components and warehouse stock. Do not substitute visually similar seals without approval.
Practical checklist
- Valve and accessory identification recorded.
- Critical wear items selected for the actual duty.
- Storage and shelf-life guidance available.
- Repair instructions and required tests included.
