ZFV Alloy steel wafer triple offset butterfly valve.

Corrosion problem  is one of the greatest hazards of chemical equipment, with a little careless, equipment damaged which cause accidents , even lead to disaster . It’s not always right to choose an same austenite stainless steel such as A351 CF8M for all the corrosive-medium. Better to use proper material against different chemical medium.
