Pneumatic wafer double disc valve

The pneumatic wafer type parallel double disc ceramic lined discharge valve (also recognized as a compact ceramic double slide valve) is a premium severe-service piping element engineered specifically for material feeding, dumping, and isolation within dense-phase pneumatic conveying lines. Featuring a highly integrated, space-saving wafer body configuration, this valve dramatically decreases face-to-face pipeline footprint requirements. Driven by top-mounted dual-acting linear cylinders, the independent dual floating discs slide flat across the hardened internal ceramic seat rings. This dynamic movement ensures a self-cleaning action that continuously sweeps away dry ash, dust, or granular crusts, effectively preventing material jamming and ensuring reliable pressure isolation under erosive environments.
