The dry ash gate valve is designed for both inlet and outlet pipelines. It features an internal flashboard that connects to a lifting mechanism. The chamber adjacent to the flashboard is connected to the flashboard's main chamber, and a ribbed slab is positioned between the flashboard and the discharge channel to prevent clogging, with a discharge port on the ribbed slab to ensure unobstructed flow. This gate valve is known for its easy operation, reliable sealing, and durability, making it ideal for use in thermal transport systems handling dry ash, fly ash, cement, and similar materials.
