The stainless steel knife gate valve adopts a full-circle channel design, and a wear-resistant folded cone made of polytetrafluoroethylene, a mud scraper, a polygrease or a wear-resistant cast iron containing Ni is installed on the upper end of the knife gate valve. At the inlet end, multiple flushing ports can be arranged around the valve body. The bottom end of the blade is machined into a blade, with high smoothness and good sealing.



      The stainless steel knife gate valve has the advantages of simple and compact structure, reasonable design, light-weight material, reliable sealing, light and flexible operation, small volume, smooth passage, small flow resistance, light weight, easy installation and disassembly, etc. It can be operated at a working pressure of 1.0MPa -2.5MPa, it works normally when the temperature is -29-650℃. The gate of the stainless steel knife gate valve has a shearing function, which can scrape off the adhesive on the sealing surface and automatically remove the sundries. The stainless steel knife gate valve can prevent the seal leakage caused by corrosion.
