Knife Gate Valve absorbs the advantages of technology and structure both at home and aboard to exclude other knife gate valves' shortcomings when using .It's a kind of lightweight, compact, simple structure, reliable sealing and long service life, and can cut off media, etc. The sealing principle is that when the gate is closed to the end, oblique plane of gate valve encounters wedge block of gate to close to achieve sealing effect, which makes the valve less blockage media. Its structure can be made into a hard seal, soft seal. Sealing requirements base on customer's selection.
