Material & Applications

Why Stainless Steel CF8M: Full CF8M construction means body, ball, and stem are all SS 316. No carbon steel components in contact with process fluid or exposed to external corrosion. Specified when the external environment is also corrosive (coastal, chemical plants, offshore) or when the piping specification requires matching body material throughout.

Typical applications: Chemical process isolation, pharmaceutical, food & beverage, seawater, marine, desalination, and any application requiring full corrosion resistance in both body and internals.

Stainless Steel CF8M Ball Valve FAQs

Why full SS body instead of WCB body with SS ball?
WCB body with CF8M ball/stem works for most applications and is more economical. Full CF8M body is specified when: (1) the external surface is exposed to corrosion (coastal/marine, chemical splash zones), (2) the piping specification requires matching material throughout, or (3) complete corrosion resistance is required for regulatory compliance.
Is CF8 (SS 304) also available?
Yes. CF8 body with CF8 ball is available for general corrosion resistance where chloride/pitting resistance is not critical. CF8M (SS 316) is preferred for chloride-containing fluids, seawater, and marine environments.
