Eccentric butterfly valve has many advantages like simple structure, light weight, short structure and easy assembly. However, sealing face of metal sealing butterfly valve is easy to be abraded by gas-solid mixture and slurry containing high-hardness solids, which will cause leakage easily. Combining structure advantage of metal sealing butterfly valve with good performance of structure ceramics, we design CBUT series ceramic sealing butterfly valve.
CBUT series ceramic sealing butterfly valve is wafer connected. Body material could be carbon steel, stainless steel according to working conditions. If customers have special requirement, forged body is optional. Sealing ring of disc and seats are made of ceramics, so that sealing face will not be eroded and abraded by medium and make
sure of sealing performance during long-time usage.
FOYO CBUT series ceramic sealing butterfly valve is eccentric design. When valve is open, sealing ring of disc and seat departs, which will reduce open torque effectively. When valve is closed, sealing ring of disc and seat will make a shear effect to cut off solid and fiber in the medium to avoid foreign things getting stuck in the
valve or cause leakage. Sealing ring of disc and seat are made of high performance
structure ceramics. ZrO2,99%Al2O3, solid tungsten carbide,Si3N4 are available for different working conditions.
Sealing ring of disc and seat sealing is sphere sealing. It makes use of advanced technology and machining equipment. After precise grinding, sealing level could reach ANSI/FCI 70-2 V.
Actuated method includes bare stem, gear, pneumatic actuator, electric actuator and so on. Bracket connections are designed according to ISO 5211.
