[Basic Information]
Manual Knife gate valve (Knife gate valve) compact design, occupy a small space, light weight, easy to install, wear anti-blocking measures perfect, easy maintenance, long service life. Depending on the requirements, multiple flushing ports may be provided around the valve body, flush directly with air, steam or water to prevent the sediment from accumulating and to be particularly suitable for fluid inflow. Polyester or Ni- resistant wear-resistant cast iron is mounted on the inlet end of the knife gate to prevent the particles from being washed directly on the seal, thus improving the working conditions and prolonging the life. In the top of the board installed Teflon, scraper, to prevent dust and gravel and other scratched material into the packing box. The use of all-round channel design, the bottom of the blade into a knife blade, high finish, to ensure a good seal.

[Valve Features]
1, ultra-short structure length, save material, can greatly reduce the overall weight of the pipeline system.
2, take up effective space is small, can effectively support the strength of the pipeline, can reduce the possibility of pipeline vibration.
3, the gate selection of austenitic stainless steel, corrosion resistance greatly improved, can be effectively prevented due to gate corrosion caused by sealing leakage.
4, the use of flexible PTFE packing, sealed and reliable, light and flexible operation.
5, the gate has a knife function, can effectively cut off all kinds of debris in the media.
6, such as the use of hard-sealed stainless steel, valve do spray welding, then you can very good expansion of the valve temperature, pressure requirements.
[Adaptation]
Knife gate valve products are widely used in chemical, coal, food, sewage, paper, steel and other areas, is an ideal sealing valve.
