Basic Info of CF8C Butterfly Valve
-
Compared to CF8M discs, the CF8C butterfly valve prioritizes weldability and high-temperature stability over pitting resistance in chloride environments.
-
CF8C’s Nb stabilization prevents carbide precipitation at high temperatures.
- Standard structure,Thick casting,Quick and light opening and closing, convenient maintenance.
-
CF8C butterfly valve handles higher corrosion temperatures.
-
Soft EPDM seat provides bidirectional zero-leakage (Class VI) for water, mild acids, and slurries.
