Abrasion resistant ash discharge valve

The manual rising stem ceramic lined slurry gate valve is a severe-service fluid control solution specifically developed for high-abrasion gravity feeding and bottom discharge applications. Utilizing a dependable manual handwheel transmission linked to a high-tensile rising screw stem, this valve provides predictable linear positioning. The entire internal flow channel and structural seating boundary are completely lined with premium structural engineering ceramics, creating a nearly diamond-hard barrier against abrasive wear. This robust layout ensures that high-velocity particles, mining tailings, fly ash, and bottom crystals never erode the outer metallic pressure envelope, ensuring superior service longevity compared to standard alloy gate valves.
