Ceramic Butterfly Valves
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 condition. Sealing ring of disc and seat sealing is sphere sealing. It makes use of advanced technology and maching equipments. After precise grinding, sealing level could reach ANSI/FCI 70-2 V. Actuated method includes bare stem, gear, pnenmatic actuator, electric actuator and so on. Bracket connections are designed according to ISO 5211.
Structure ceramtics has wonderful chemical stability, which makes sure that ceramic sealing face to butterfly valve will keep good sealing after long times of usage in all kings of strong acid and strong alkali medium.Currently, FOYO CBUT series ceramic butterfly valves have showed great performance in steel mill, metallurgy, mining, pulp&paper, environment protection, etc.
