  • Product description
  • Technical parameters
 Our ultra-thin Knife Gate Valve is engineered for superior performance, boasting key advantages such as compact dimensions, lightweight construction, minimal flow resistance, and a slag-free design. Its streamlined structure allows for effortless installation and disassembly, effectively overcoming the inherent limitations of conventional valves—including high flow resistance, bulky footprint, susceptibility to slag accumulation, and complex maintenance associated with standard gate valves, ball valves, globe valves, and butterfly valves. As a result, it has become the preferred replacement for numerous general on-off and control valves in critical industrial processes.
