Knife gate valve has simple and compact structure. It uses knife gate plate to cut off medium and has good sealing performance.The cast iron knife gate valve has the characteristics of low fluid resistance, easy and quick opening and closing. The ductile iron knife gate valve is wear-resistant, corrosion-resistant, long service life and suitable for various media.In terms of application, the knife gate valve is used in water, paper making, sewage treatment and other industries. For example, sewage discharge pipeline, slurry conveying pipeline, etc., can rely on knife gate valve to accurately control the medium opening and closing, to ensure smooth operation of the process.
