[Basic Information]
Manual knife gate valve (knife gate valve) compact design, occupy a small space, light weight, easy to install, wear anti-blocking measures to improve, easy maintenance, long service life. According to need, multiple flushing ports can be set around the valve body to directly flush with air, steam or water to prevent the gradual accumulation of sediment, which is especially suitable for the difficult fluid input. Polyester or nickel- plated wear-resistant wear-resistant hemming cone installed at the entrance of the knife gate valve to prevent the direct erosion of particulate matter in the seal, which can improve the working conditions and prolong life. Teflon is mounted on the upper edge of the blade, scraper to prevent the abrasive material such as dust grit from entering the stuffing box. The use of full circular channel design, knife blade into the bottom process, high finish, to ensure a good seal.

[Valve Features]
1, short structure length, save material, can greatly reduce the overall weight of the piping system.
2, take up less effective space, can effectively support the strength of the pipeline, reducing the possibility of pipeline vibration.
3, the gate selection of austenitic stainless steel, corrosion resistance greatly improved, which can effectively prevent the leakage caused by the gate seal leakage.
4, the sealing packing with flexible PTFE, reliable sealing, light and flexible operation.
5, the gate with a knife function, can effectively shut down all kinds of debris in the media.
6, such as the use of hard-sealed stainless steel, valve do spray welding, it can be a good extension of the valve on the temperature and pressure requirements.
[Adaptations]
Knife gate valve products are widely used in chemical, coal, food, sewage, paper, steel and other fields, is an ideal seal valve.
