The Pneumatic Ceramic Lined Double Disc Knife Gate Valve is the ultimate solution for extreme abrasion and erosion. It features high-alumina ceramic liners on all wetted parts and a unique double-disc design that creates a pressurized seal. Driven by a pneumatic actuator, the discs rotate or slide to shear through hard scales and fly ash. This valve is specifically engineered for pneumatic conveying, mining tailings, and coal-fired power plant systems where standard metal valves fail within weeks
