CHENYU VALVE is proud to announce that its stainless steel ball valves have been successfully installed and put into operation at a large-scale chemical plant, receiving positive feedback from the client's technical and maintenance teams.
The valves are being used in critical sections of the plant's fluid control systems, including corrosive media pipelines and high-pressure flow lines. Thanks to their superior corrosion resistance and robust construction, the stainless steel ball valves have demonstrated excellent performance under continuous operation and harsh chemical environments.
Engineers on-site also praised the valves' smooth operation, minimal maintenance requirements, and long service life. The installation process was efficient, and the valves integrated seamlessly into the plant's existing system.
Before switching to CHENYU’s stainless steel ball valves, the chemical plant experienced frequent issues with conventional valves, including:
Corrosion-induced leakage from carbon steel bodies handling aggressive chemical compounds.
High maintenance frequency due to seat wear and stem seal failure, leading to costly downtime.
Difficult operation caused by high torque and galling of threaded components.
CHENYU’s engineering team proposed a tailored solution: stainless steel floating ball valves (CF8M body, PTFE seats, and anti-static design) for the plant’s corrosive media lines, and trunnion ball valves for high-pressure sections. The result: zero leakage after six months of continuous operation, and operators reported a 60% reduction in manual operating torque.
The following CHENYU ball valve models were installed:
| Parameter | Details |
|---|---|
| Valve type | Floating ball valve (for corrosive lines) / Trunnion ball valve (for high-pressure lines) |
| Body material | CF8M (316 stainless steel) – for corrosion resistance |
| Seat material | PTFE (virgin grade) – low friction, chemical resistant |
| Size range | 2″ – 8″ (DN50 – DN200) |
| Pressure rating | Class 150 – 600 LB |
| End connections | Flanged (ASME B16.5) |
| Design standard | API 608 / API 6D |
| Testing | API 598 (zero leakage) |
| Special features | Anti-blowout stem, anti-static device, fire-safe design (optional) |
Three months of operation data compared to the previous valves:
| Metric | Previous Valves | CHENYU Stainless Steel Ball Valves |
|---|---|---|
| Leakage incidents | 3 per month | 0 |
| Maintenance stops | 2 per quarter | 0 |
| Operating torque (N·m) | 45 – 60 | 18 – 22 |
| Estimated service life | 12 – 18 months | 50,000+ cycles (projected) |
All CHENYU stainless steel ball valves supplied to this chemical plant meet or exceed:
API 608 / API 6D – Design and manufacture
ASME B16.34 – Pressure-temperature rating
API 598 – Inspection and testing (100% hydrostatic and air seat test)
NACE MR0175 – For sour service (optional, available on request)
Fire-safe – API 607 / ISO 10497 (certified upon request)
