Abrasion resistant ceramic lined dome valve

The pneumatic rotating swing disc gate valve is a severe-service industrial valve designed for automated feeding and isolation of bulk solid materials, dry powders, and abrasive particles within pneumatic conveying lines. Powered by a high-thrust linear pneumatic cylinder and a robust external lever mechanical arm, the internal disc swings and rotates across the seating surface during every cycle. This unique shearing action naturally sweeps away material accumulation and prevents clogging. Enhanced with a high-purity abrasion-resistant ceramic inner lining, this valve delivers exceptional operational longevity and bubble-tight sealing in coal-fired power plants, steel mills, cement dosing lines, and mining operations.
