Knife gate valve use occasions and suitable medium

Knife gate valve is a special kind of gate valve. Although this kind of valve has been introduced a lot before, I found that some friends still don’t know much about it. For example, where is the knife gate valve used? What media is it mainly suitable for? Below I will answer it for you.

     For ordinary gate valves, many people must be familiar with them, knowing that they have problems of heavy weight, large flow resistance, and difficult installation, and the emergence of knife gate valves just solves these problems.

The knife gate valve can replace the general shut-off valve, and can work under the working pressure of 1.0MPa-2.5MPa and the operating temperature of -29-550℃. The gate of the knife gate valve has a shearing function, which can scrape off the adhesion on the sealing surface and automatically remove the sundries. The stainless steel gate can prevent seal leakage caused by corrosion.

     The use occasions and applicable media of knife gate valve are:

     1. Mining, coal washing, iron and steel industry - used for coal washing and washing pipelines, slurry filtering pipelines, etc., ash discharge pipelines;

     2. Purification device - used for waste water, mud, dirt and clarified water with suspended solids;

     3. Paper industry - used for any concentration of pulp and feed-water mixture;

     4. Power station ash removal - used for ash slurry.
