- Applications: Lime Stone Slurry, Gypsum Slurry in FGD system
FGD takes use of lime stone slurry to remove Sox, Nox from flu gases and produces gypsum slurry as a by-product. The biggest technological challenges of FGD systems are the high corrosion and abrasion of lime stone slurry that cause leakage of pipes and valves.
Frequently replacement of valves and maintenance will reduce efficiency and increase cost.
FOYO FCBV ceramic ball valve is fully lined with ceramics, so that medium will not be in touch with metal body directly to avoid corrosion/abrasion of body. By using FOYO FCBV ceramic ball valve, stability and service life of valves/pipes can be improved significantly, so efficiency of FGD system could be increased while cost of FGD
system could be reduced.
FOYO offers O port and V port as options. V port ceramic ball valves have better equal percentage flow regulation, which could be used as control valves.
Three pieces design of FCBV series forged ceramic ball valves could make sure of flexible assembling dimensions. Flange dimensions and face to face of valves could be designed per customers' special requirements, so that ceramic ball valve could be assembled on the pipeline without any modification of current pipe and salve assembling cost.
All trims of valves (including ball, seats, bushing, lining and stem, etc) have been precisely designed and machined to make sure that body of valve will not be in touch with medium directly and body of valve will not be corroded or abraded by medium. Sealing faces of ceramic ball and ceramic seats have been polished by advanced technique and machines. After precise grinding, all leakage level of FCBV series forged ceramic ball valves could reach ANSI/FCI 70-2 Class VI(zero leakage).
Actuation of FCBV series valves includes lever, bare stem, worm gear, pneumatic actuator and electric actuator, etc. Mounting pad is designed according to ISO 5211.
>99%Al2O3, ZrO2, Si3N4, SSiC are made by Cold isostatic pressing molding and high sintering. All these ceramics will not interact with almost all organic solvent and inorganic chemical medium (except hydrofluoric acid), so ceramics will not contaminate medium. Solid Tungsten carbide( STC) has good mechanical performance and thermal-shock performance, which is suitable for high temperature, high pressure and high abrasive working conditions.
Structure ceramics has wonderful chemical stability, which makes sure that physical property and chemical property of ceramic trims will not change after long times of usage in all kinds of strong acid and strong alkali.
FOYO FCBV series forged ceramic ball valves have showed great performance in various severe highly corrosive working conditions of steel mill, metallurgy, Petro-chemical, mining, coal-fired power plant, paper & pulp, polysilicon, etc.
FOYO's experienced engineers will select the most suitable material and solution for different working conditions.
