Parallel Double wedge structure
Used as dischrage valve and bleeder valve
Wedge with function of
Excellent Anti-abrasion performance
Body seat and disc sealing
ring of ceramic double wedge gate valve in material of ceramic with extreme
hardness are wear resistant against friction in pneumatic conveying of powder
and abrasive slurry with hard solid content in industries of steel, metallurgy,
petrochemical, mining, power plant, paper, pulp and polysilicon etc.
Excellent Anti-corrosion performance
The ceramics are inert to
almost all organic and inorganic chemicals.
Strong stability in
strong corrosive slurry avoids pollution to the service.
Much longer service life
Service life of seat and disc
with ceramic is many times of that with stainless steel.
