Industry Applications
Station Check Valves are widely used in pipelines and systems where backflow prevention is critical:
Material customization plan
Customized 316L stainless steel valves forGerman chemical enterprises. Resistant tostrong corrosion, suitable for their acidicmedium transportation systems, with aservice life extended to over 8 years.
Structural optimization design
For the Saudi desert project, the valve stemsealing structure was changed to a doublebellows design to address the leakage issuein the high-temperature and dustyenvironment, and it was highly recognizedby the customers.
Interface standard adaptation
Customized API 600 standard valves for acertain company in the United States. Theflange size is fully compatible with ANSIB16.5, ensuring zero error during on-siteinstallation and reducing the constructionperiod by 30%.
