Pneumatic Ceramic Knife Gate Valve for Ash, Slurry, Acid. Anti-corosion and wear-resisting,DN50~300
Product Description:
Ceramic knife gate Valve is suitable for corrosive medium with high hardness of particles (such as slag water), or soft particles in pipeline. The products are widely used in ash, sludge, coal slurry, pulp, sewage and other solid, especially for stone coal system for thermal power plant.
 Disc and seat sealing surface adpot an advanced ceramics materials technologies for abrasion resistance, corrosion resistance, high temperature resistance. Therefore, this valve has a very high abrasion resistance, corrosion resistance, and good insulation, low thermal expansion.
This valve outlet is full circulation without blocking, good abrasion resistance and sealing performance. Opening-load is low, and there's less ash jam phenomenon.
This valve has ductile structural ceramic sealing, high mechanical strength, good abrasion resistance, long life durability. The structure is compact and can be installed at any angle.
 Norminal pressure: PN10~PN25.Â
Applicable temperature:≤250ºC.Â
Actuator Pressure: 0.6~0.8MPa.Â
 It can be designed according to customer's requirement.
