Electric knife type valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, flexible operation, small volume, smooth channel, small flow resistance, light weight, easy installation, easy disassembly and other advantages, can be in 1.0MPa-2.5MPa working pressure, working -29-650℃ normal use condition. The knife gate valve has cutting function, it can scrape off the adhesive on the sealing surface, automatically remove sundries, and the stainless steel gate can prevent the sealing leakage caused by corrosion.

1, ultra short structural length, saving material, can make the whole weight of pipeline system is greatly reduced.
2, the use of small space, can effectively support the strength of the pipeline, can reduce the possibility of pipe vibration.
3, the selection of austenitic stainless steel gate, corrosion resistance greatly improved, can effectively prevent the gate corrosion caused by the leakage of seal.
4, the sealing packing adopts flexible PTFE, reliable sealing, easy and flexible operation.
5, the gate with the knife, can effectively brake off all kinds of debris in the medium.
6, such as the use of hard sealing stainless steel, the valve to do spray welding treatment, it can be a good expansion of the valve temperature, pressure requirements.
Knife gate valves are widely used in industries such as chemicals, coal, food, sewage, paper making, steel, etc., and are ideal sealing valves.
