COVNA HK59-D-D Air Operated Knife Gate Valve
The pneumatic knife gate valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, light and flexible operation, small volume, smooth channel, small flow resistance, light weight, easy installation, easy disassembly and so on. It can work normally under the working pressure of 1.0mpa-2.5mpa and operating temperature of – 29-650 ℃. The gate of knife gate valve has the function of shearing, which can scrape off the adhesive on the sealing surface and automatically remove the sundries. The stainless steel gate valve can prevent the sealing leakage caused by corrosion
