Bidirectional knife gate valves of PA 520 series
|
PA 520 series knife gate valves are designed to block the flow of liquids with a content of suspended solids up to 5%. Wafer-type connection to the pipeline. The seat design, accuracy and quality of the components make it possible for the knife gate valves of this series to reliably shut off the working medium flow in any direction. PA 520 series valves can be made of cast iron, carbon steel, various types of stainless steel, based on customer requirements. Due to reliability and simplicity of the design, the use of high-quality materials and components, PA 520 series knife gate valves are widely used in various industries. Main applications: – paper-and-pulp industry; – mining industry; – chemical industry; – treatment plants, sewerage networks; – food industry
