MODERN Knife Gate Valve (for Fluids, Slurries and Dry products)

Application:

  •  Sewage treatment plants
  •  Chemical & raw Material industries
  •  Food Industry
  •  Mining and allied industries


“When space is a limiting factor, the liquid has fibrous substance that can get lodged in the bottom cavity of a valve body, the hydraulic heads moderate, a Knife Gate Valve can do the job admirably.  However, exercise caution when choosing a knife gate valve over the time tested Gate Valve”

The minimum stress point in a knife gate valve is somewhere near the major axis between the two vulnerable section probably where the short and long side join. Therefore provide as large a fillet radius as possible as stress here appreciably increases with diminishing radius. A square cornered chest would induce abnormally high stress. The reason why all pressure vessels are rounded with no sharp corner.
