Ceramic Ball Valve
Characteristics
This valve is applicable as an on-off or pipelines with high hardness grains or with both soft gralns and corrosive media. Its nominal pressure is 1.6MPa, and applicable temperature <=200°C. All medlum-contacting parts are made of structural ceramic, featuring extremely high chemical stability and hardness (Rock well Hardness HRC90), only next to diamond. Therefore, this valve has extremely strong resistance to abrasion, corrosion anc erosion, good heat insulation and small thermal expansion.
The ball body is made with advanced grinding equipment and process, with high-precisior ball roundness and good surface quality, and after facing-up with the valve seat, a good seal abllity can be obtained by means of self-lubrication of Zr02 ceramic, thanks to the ceramic’s strong resistance to abrasion, this valve is durable and extremely rellable, with a long service life being 2-4 times of that of Ti alloy and Monel valves.
