Flanged check valves are key in pipeline systems. They stop reverse flow, protecting pumps and equipment. Fergo offers four models: RV430, ZV116, RV450, and ZV216.
These models vary in pressure and temperature ratings. The RV430 and RV450 handle up to PN40 (40 bar) and +450°C. The ZV116 and ZV216 are rated for PN16 (16 bar) and +350°C.
The materials used define their limits. Steel-housed valves like RV430 and RV450 handle heat and pressure well. The ZV116 and ZV216, with cast iron bodies, are for higher temperatures and milder conditions.
Corrosion resistance is also a key factor. The RV450, made of stainless steel, is great for acids and chemicals. The RV430 suits deman...

Corrosion resistance is also a key factor. The RV450, made of stainless steel, is great for acids and chemicals. The RV430 suits demanding media like steam and hot water. The ZV116 and ZV216 are good for water, air, and oil.
Flanged lift check valves have big advantages. Their spring-assisted mechanism closes quickly and securely. This is crucial for preventing dangerous pressure surges.
Swing check valves close slower and rely on gravity. They're best for horizontal pipelines. Lift check valves seal better and prevent leaks.
Choosing the right flanged non-return valve depends on the application. For high-pressure and temperature, RV430 and RV450 are best. RV450 is top for corrosive media. For water or compressed air systems, ZV116 and ZV216 are cost-effective. Their design makes them more reliable than swing check valves.
Flanged Lift Check Valves PN16/25/40
Flanged check valves deliver reliable performance and are indispensable for systems that must prevent the backflow of liquids. Fergo offers a wide range of flanged check valves in various sizes from DN15 to DN250 and pressure ratings of PN16, PN25, and PN40. Our products are manufactured from high-quality materials such as stainless steel, carbon steel, cast iron, and ductile iron, and are equipped with spring loading to ensure reliable operation. Whether you operate in the chemical industry, food processing, or other sectors, our flanged check valves provide the necessary protection against backflow and ensure the safe operation of your systems.
