Manual of ceramic ball valve with lever
Applocation :
Ball valve is made up of cock , its opening and closing is ball ,using ball aroud the axis of stem rotate 90 C to relization of opening and closing . Ball valve is mainly used for cuting , distribution and change the flow direction of medium in the line . Ceramic ball valve is a new knid of corrosion resistant ball valve .All of the ball , seat and everywhere the medium flow is made of ceramic in order to substrate from corrosion , sybstrate coated with a layer of enamel , then use ceramic lining . It is mainly used for electria power , petroleum , chemicial piping sustem such as the opeing and closing device .
Characteristics :
The valve is appliation as an on-of or piplines with high - hardness or with both soft graun and corrosive medium . Its mominal pressure is 1.6 Mpa , and applicable temperature ¡Ü200¡æ
All medium - contacting parts are made of industricial ceramic , featuring extremely high chemical stability and hardness ( Rockwell Hardness HRC90) ,only nest to diamond . there fore this valve has extremely strong resistance to abrasion corrosion and erosion , good heat insulation and small thermal expansion . The ball is made with advanced grinding equipment and process , with high precisiom ball roundness and good surface quality , and after facing -up with the valve seat ,a good sealability can be obtained by means of self - lubrication of ceramic .
Thanks to the ceramic¡¯s strong resistance to brasion , this valve is durable and extremely reliable with a long service life
