Pneumatic ceramic double disc valve

The pneumatic parallel double disc ceramic lined gate valve (commonly known as a ceramic double slide valve) is a premium severe-service piping component custom-engineered for automated isolation in dense-phase pneumatic conveying systems. Driven by a top-mounted, high-thrust linear air cylinder, the valve features dual independent gates that slide parallel against hardened ceramic seats. This sliding action forces the discs to rotate slightly during operation, creating a powerful shearing action that continuously scrapes away material deposits and prevents particulate jamming. Fully lined with ultra-hard structural engineering ceramics along the entire wet flow path, this valve provides exceptional resistance to severe erosion from dry fly ash, pulverized coal, cement, and mining dust.
