Ceramic knife gate valves, also known as ceramic knife-shaped gate valves, ceramic wear-resistant knife gate valves, thin ceramic slag valves, and thin ceramic slurry valves. The shut-off device is the gate plate, which moves perpendicular to the fluid direction, cutting the medium with a knife-shaped plate that can slice through fibrous materials. The valve body of the ceramic knife gate valve actually has no chamber; the gate plate rises and falls in the side guide groove and is securely pressed against the valve seat by the bottom lugs. For higher medium sealing, an O-shaped ceramic sealing valve seat can be used for double-sealing. The ultra-short structural length saves materials and reduces the overall weight of the piping system; it occupies less effective space, effectively supporting pipeline strength, reducing pipeline vibration, and is suitable for installation at any angle on pipelines with different layouts. Specifically designed for solid-liquid two-phase flow medium pipelines, it features a structural form designed to resist throttling erosion, fulfilling both shut-off and shut-off + throttling dual functions for such pipeline media.
