FCCV8 Double Lining Ceramic Ball Valve
Structural characteristics and advantages
- ● Double lining, double sealing: ensures enhanced safety and corrosion protection.● Molded PTFE lining with dovetail groove fixation: prevents peeling or detachment.● Split-body design with minimized cavity: avoids material accumulation, reducing leakage risks.● Ceramic flow passage: guarantees high resistance to abrasion and chemical attack, extending valve lifespan.● Enhanced external protection: preserves the integrity of the metal outer wall, reducing maintenance costs.
