PFA Lined Swing Check Valve

Vibron9

The GFT9-lined Swing Check Valve Vibron9 is specifically designed to prevent backflow or back pressure in industrial systems, making it a critical component for maintaining system integrity. With a temperature range of -40°C to +150°C, its fully lined design ensures maximum protection against corrosion and contamination, making it the ideal choice for applications involving highly corrosive, reactive, pure, permeating, or even abrasive media. This valve excels in industries such as chemical processing, pharmaceuticals, petrochemical, mining, and pulp & paper, where robust performance and minimal maintenance are paramount.

The GFT9 Vibron9 is particularly effective when traditional materials, like stainless steel or plastics such as PVC, PVDF, and PP, fall short in resisting corrosion. Its wide range of lining alternatives provides tailored solutions for numerous corrosive environments, while the metal pressure-bearing body offers enhanced strength, making it perfect for high-pressure applications. This design ensures reliable performance in tough conditions, offering the superior durability needed for demanding industrial processes.

Industry Applications

The GFT9 PFA-lined Swing Check Valve is widely used in industrial applications where backflow prevention and corrosion resistance are crucial. Its fully lined design ensures maximum protection against harsh chemicals, even in highly reactive or abrasive environments. This makes it ideal for sectors like chemical processing, petrochemical, pharmaceutical, and mining industries, where contamination control and durability under high-pressure conditions are essential. Thanks to its corrosion resistance, the valve outperforms traditional stainless steel and plastic valves, ensuring safe fluid transport in systems dealing with aggressive media.

The valve's versatility extends to many critical operations such as wastewater treatment, pulp and paper manufacturing, and oil and gas processing, where contamination risks and high pressures are prevalent. By incorporating a range of alternative linings, it offers tailored solutions for applications handling a variety of challenging chemicals and media. Its ability to operate efficiently even in high-pressure settings makes it a trusted choice for industries requiring robust and long-lasting performance
