Pneumatic- Manual Ceramic Ball valve

Characteristics


This
valve is application as on-off or
pipelines with high-hardness grains or wwith both soft grns and corrosive
medium .Its nominal pressure is 1.6Mpa
,and applicable temperature ≤200℃ .And
air supply pressure 0.6-0.8 Mpa .All medium contacting parts are made of
structure ceramic ,featuring extremely high chemical stability and hardness (Rockwell
Hardness HRC90 0),Only next to diamond .Therefor ,this valve has
extremely strong resistance to abrasion ,corrosion and erosion ,good
heat insulation and small thermal expansion the ball body is made with advanced
grinding equipment and process with high –precision ball roundness and good
surface quality ,and after facing –up with the valve seat ,a good seal ability
can be obtained by means og self-lubrication of Zr02CERAMIC .thanks to the
ceramic`s strong resistance to abrasion ,this valves is durable and extremely
reliable with a long service life being 2-4 times of that Ti alloy and Monel valves
