1. The sealing pair of gate plate and seat for ceramic knife gate valve adopts structural ceramic, wear resistant and corrosion resistant, which can be selected according to particle medium working conditions.
2. Structural ceramic has excellent hardness and chemical stability, anti erosion and low thermal expansion coefficient, suitable for highly abrasive media such as abrasive particles, slurry and ash slag.
3. Short pattern valve body design with high mechanical strength and long service life, compact construction, permitting installation at any angle.
4. Full bore flow passage, low operating torque, less ash accumulation and jamming, reliable sealing performance.
5. Valve body designed in accordance with ASME B16.34.
6. Widely used for on off service of pipelines carrying hard particle media (ash slag water), soft particles and fibrous media. Suitable for conveying liquid solid and gas solid two phase media including ash slag, sludge, coal slurry, ore slurry and sewage, especially for coal gravel system of thermal power plant.
1. Mated ceramic sealing pair with high hardness, resistant to particle erosion wear, greatly extended service life compared with metal knife gate valves.
2. Straight through flow passage without dead zone for medium retention, preventing slurry accumulation and jamming.
3. Knife type gate provides shearing capacity to cut off fibrous and coarse particle materials.
4. Replaceable ceramic seat, it can be replaced on site after damage without replacing the whole valve.
5. Metal valve body provides structural strength while ceramic is only applied for sealing trim, balancing structural strength and wear resistance.
6. Multiple actuator options manual, pneumatic and electric, suitable for automatic slurry pipelines.
