Knife gate valve material: cast iron, cast steel, carbon steel, stainless steel, fluorine-lined, etc. Knife gate valve seal: hard seal, soft seal, single-sided seal, double-sided seal and other material seals.
The thin knife gate valve has the advantages of small size, small flow resistance, light weight, easy installation and easy disassembly, etc. It solves the large flow resistance and heavy weight of ordinary gate valves, flat gate valves, ball valves, globe valves, regulating valves, butterfly valves and other valves. , difficult installation, large floor space and other difficult problems. After the appearance of the knife gate valve, a large number of general-purpose shut-off valves and regulating valves have been replaced by them. Up to now, the amount of knife gate valve is from Japan and Japan.
Knife gate valves are used in the following areas:
- Mining, coal washing, iron and steel industry – used for coal washing and washing pipelines, slag filtering and slurry pipelines, etc., ash discharge pipelines;
- Purification device – used for waste water, mud, dirt and clarified water with suspended solids;
- Paper industry – used for any concentration of pulp, material-water mixture;
- Power station ash removal – used for ash slurry.
