Manual ceramic knife gate valve

The manual ceramic seated knife gate valve is a severe-service flow control component designed to handle fluids laden with sharp solid particles, abrasive powders, and corrosive slurries. Operated by a reliable manual handwheel with a rising stem for position indication, this valve completely encapsulates the internal flow passage with industrial-grade, high-purity structural ceramics. By utilizing a "ceramic-on-ceramic" sealing interface, the valve prevents solid particles from damaging the metallic pressure-containing envelope, significantly extending the service lifespan in power generation, chemical processing, and mining industries where standard alloy valves fail due to rapid erosion.
