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.
