Unidirectional knife gate valves for high pressure with blind body of PA 570 series
|
PA 570 series knife gate valves are unidirectional valves in a cast body, primarily intended for high pressure applications. These valves are used to transport liquids with a suspended particles content of up to 5%. The most demanded valves are DN 600-2000. Valves can be manufactured with an operating pressure of up to 25 kgf/cm2 and can be used on large-diameter pressure pipelines where conventional knife gate valves cannot provide the required tightness. PA 570 series valve body can be made of cast iron and various steel grades as required by the customer and has a double gland packing both in the knife's flow area through the body and in the stem outlet area, which causes high reliability and tightness of these valves of especially large diameters.
