Parallel Double wedge structure

Used as dischrage valve and bleeder valve

Wedge with function of self-cleaning

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.
