Slide Gates and Knife Gate Valves for Dry Bulk Powder Processing

Our customers often requests “knife gates” when  what they are really looking for is a “slide gate” for dry bulk  material handling. These two types of gates are often confused with one another, but a knife  gate and a slide gate are NOT the same.  A  knife gate valve is a component that uses a blade to cut through very thick liquids or hard clumps of clogged material. A slide gate valve is a component  that utilizes a stainless steel, rectangular slide plate to shut off or open the flow of dry material. The slide plate actuates between two, compression-loaded, hard polymer plates. Knife Gates and Slide Gates are used in a wide variety of industries, including Food, Plastics & Petrochemical, Animal Feed, Energy, Mining & Minerals, and Chemical Industries.
