The valves on the hydraulic slag removal pipeline use slurry as the conveying medium, operating under conditions of continuous erosion, abrasion, ash deposition, and severe scaling caused by ash slurry. Common issues in such conditions include rapid wear, short service life, difficulty in opening and closing, inadequate sealing upon closure, and inconvenience in operation, leading to frequent maintenance. Our company has developed ceramic slag discharge valves, which are highly suitable for this system.
