A ball valve is built for durability—but like any mechanical component, it doesn’t last forever. Over time, seals wear out, materials degrade, and operation becomes unreliable. Knowing exactly when to replace a ball valve can save you from costly leaks, shutdowns, or even safety hazards.
At Perfect Engineers, we supply long-life ball valves—but we also help industries determine the right time to replace old or faulty valves with fresh, efficient alternatives.
| Valve Type | Expected Service Life |
|---|---|
| SS/PTFE Seated Ball Valve | 8–12 years (normal conditions) |
| Graphite/Metal Seated | 5–10 years (high-temp/steam) |
| PVC/Plastic Valves | 3–5 years (domestic/low pressure) |
| Sanitary/Clamp Valves | 2–3 years (CIP/SIP cycles) |
| Condition | Recommendation |
|---|---|
| Minor stem leak, body in good shape | Repair |
| Seat damage, 3-piece/top-entry design | Repair or Replace Seats |
| Cracked body, fused threads, stripped stem | Replace Entire Valve |
| Old valve (10+ years), no spares available | Replace with new generation |

Not recommended. Always use new gaskets or PTFE tape when reinstalling or replacing.
Absolutely. If your current valve has an ISO 5211 pad, we can help you install an electric or pneumatic actuator.
Use SS304/316 valves with PTFE or RPTFE seats for better durability and corrosion resistance.
