Ceramic Double Gate Valve

The ceramic double gate valve is designed for high-wear and high-corrosion applications, making it ideal for dry ash systems in power plants, silo pump discharge, mining, paper manufacturing, and chemical industries. It efficiently handles abrasive dry dust, high-hardness particles (e.g., ash slurry), and corrosive soft-particle media. With a nominal pressure of 1.0 MPa and an operating temperature of up to 200°C, it ensures durability and reliability. The valve body is constructed from WCB cast steel and seamless steel pipes, with a hard-sealing surface for enhanced wear resistance. Featuring a full-bore, obstruction-free design with a blow-blocking system, it provides complete bidirectional sealing when closed. The pneumatic operation requires an air pressure of 0.6–0.8 MPa.
