Pneumatic knife gate valve

Knife gate valve is a kind of valve designed for medium containing solid particles or fibrous media, widely used in sewage treatment, paper making, mining, chemical industry and environmental protection and other working conditions. The valve is suitable for sludge, slurry, sediment and other media, can effectively cut off the fluid containing impurities, to avoid valve clogging and damage. Knife gate valve adopts thin blade gate design, compact structure, flexible opening and closing, strong cutting ability, small flow resistance. Product advantages include reliable sealing, wear resistance, corrosion resistance, easy maintenance, suitable for harsh working conditions. The main function of knife gate valve is to realize the rapid cut-off and connection of impurity-containing medium, and to guarantee the smooth operation of pipeline system. Its excellent durability and high efficiency performance, making it an important valve equipment for handling complex media in industrial processes.
