Characteristics
This stainless steel tilting disc slow closing check valve is cast from 304/316 stainless steel with outstanding acid, alkali and seawater corrosion resistance. Eccentric short-stroke disc with external hydraulic buffer achieves two-stage 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 corrosive chemical pipeline systems.

Advantages
1.Ss check valve CF8/CF8M stainless steel resists seawater, acid and alkali corrosion without rust, perfectly matches food, pharmaceutical, seawater desalination and chemical anti-corrosion pipeline projects.
2.This stop check valve adopts 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.
Packing
Standard export wooden case packaging

Application Scenarios
This disc check valve widely used in Seawater desalination pump stations, food & pharmaceutical circulating pipelines, chemical acid & alkali medium lines, coastal power plant cooling water, pure water treatment, anti-corrosion sewage systems and marine aquaculture water circulation pipelines.
