Product Details

NSV Electric knife gate valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, flexible operation, small volume, smooth passage, low flow resistance, light weight, easy to install and disassemble, etc., it can work normally under the working pressure of 1.0MPa-2.5MPa and the operating temperature of -29-650℃. Knife-type gate valve has the function of shearing, which can scrape off the adhesive on the sealing surface and remove the sundries automatically. Stainless steel gate can prevent sealing leakage caused by corrosion.
