Fill-in-the-blank: Ball valves are commonly used to shut off water-coal slurry pipelines, as ball valves have a self-cleaning mechanism, which prevents material from getting stuck at the sealing points and causing poor closure. The basic requirements for water-coal slurry pipeline isolation valves are: (abrasion resistance) and good sealing.
Metal hard-sealed ball valves have a long service life
Eccentric rotating ball valve Eccentric rotating ball valve Corrosion-resistant
Ceramic feed valve, ceramic feed valve, excellent wear resistance
Two-way hard-sealed ball valves are commonly used for shutting off water-coal slurry pipelines, as these ball valves have a self-cleaning function, which prevents materials from getting stuck at the sealing points and causing poor closure. The basic requirements for water-coal slurry pipeline isolation valves are: (no clogging) and good sealing.
