SS CF8/CF8M micro-resistance slow closing check valve

This stainless steel tilting disc butterfly check valve is cast from 304/316 stainless steel with superior acid, alkali and seawater corrosion resistance. Eccentric short-stroke disc with external hydraulic buffer achieves staged slow closing to eliminate water hammer and noise. Low flow resistance improves pump efficiency, with soft/metal sealing options. Widely used in seawater desalination, food, pharmaceutical and chemical corrosive pipeline systems.

1.304/316 stainless steel resists seawater, acid and alkali corrosion without rust, perfectly matches food, pharmaceutical, seawater desalination and chemical anti-corrosion pipeline projects.

2.Short-stroke disc plus hydraulic staged slow closing eliminates water hammer and impact noise, protecting stainless steel pumps and anti-corrosion pipelines from pressure surge damage.

3.Smooth stainless steel inner surface prevents scaling and silt jamming, avoids medium contamination, stable long-term operation with low maintenance frequency.
