| Ceramic knife gate valves are suitable for opening and closing pipelines with high hardness particles and other media, as well as soft particles but corrosive media. The product is widely used in solid, liquid-solid, gas-solid two-phase medium transportation systems such as ash, sludge, coal slurry, ore slurry, and sewage, especially suitable for pebble coal systems in thermal power plants. Manual, pneumatic, and electric driving methods can be used.
Ceramic knife gate valve
Product Introduction:
Ceramic knife gate valveSuitable for opening and closing pipelines using high hardness particles and other media, as well as media with soft particles but corrosive properties. The product is widely used in solid, liquid-solid, gas-solid two-phase medium transportation systems such as ash, sludge, coal slurry, ore slurry, and sewage, especially suitable for pebble coal systems in thermal power plants. Manual, pneumatic, and electric driving methods can be used.
The sealing surface materials of the gate and valve seat are made of structural ceramics, which are wear-resistant, corrosion-resistant, and high-temperature resistant. The sealing surface uses hard sealing and the parts in contact with the medium are all made of structural ceramic materials, with extremely high chemical stability and hardness. Therefore, this valve has extremely high wear resistance, corrosion resistance, and erosion resistance, as well as good insulation and low thermal expansion.
