What is a knife gate valve?
The knife gate valve is also known as knife gate valve. Its main function is to control the flow of liquid or gas by moving the knife-shaped valve plate up or down. The name of the knife gate valve is from its special valve structure. It is an open and closed valve, which is usually used to perform comprehensive cut off operations during the circulation of the medium.
The knife gate valve has the characteristics of simple structure, flexible switching, small starting power, super small design space, and good sealing performance. It can withstand the working environment of high temperature, high pressure, and strong corrosive media. It is usually used in pipelines systems in oil, chemical, electricity and other industries. It is a very important pipeline control device.

Advantages of the knife gate valve:
1. Good corrosion resistance
The stainless steel has excellent corrosion resistance and oxidation resistance. It can withstand various corrosive media, which is more durable and reliable.
2. Good sealing performance
The structure of the knife gate valve is implemented by compulsory sealing, rather than relying on the clamp and other auxiliary parts to achieve. Therefore, the sealing performance is very excellent ,which can effectively prevent fluid leakage.
3. Convenient maintenance
Due to the knife gate valve has simple structure, the maintenance cost is relatively low and it is easy to clean and maintain. It can ensure that the service life is sufficient.
4. Wide range of application
The knife gate valve is suitable for a variety of media such as fluid, gas, dust, food and other media. It mainly depends on the selection of valve materials and use of working conditions.
In general, the material of knife gate valve is generally ductile iron, gray iron, carbon steel, stainless steel, etc. Different materials have different corrosion resistance and wear resistance, it is suitable for different media.
Case:
Pakistan Cardboard Factory
Main products: DIN SS316 seamless pipes, DIN SS316 fittings, DIN SS316 flanges, SS knife gate valves, SS316 ball valves
This customer is the owner of a cardboard factory in Pakistan. The factory needs a lot of pipe fittings and valves. He also compared more than a dozen valve companies online, and then was deeply moved by the professional expression and enthusiasm of the business personnel of the WESDOM international department in final. And they choose to cooperate with WESDOM. Although it is the first time to cooperate with each other, but the final customer also gave us a high evaluation, WESDOM is very good!

Application:
Knife gate valves are commonly used in applications where a tight shut-off is required, such as the following:
1. Wastewater treatment:
Knife gate valves are used in wastewater treatment plants for controlling the flow of wastewater, sludge, and other fluids in pipelines, tanks, and other equipment. They are often used for slurry applications where large particles and solids need to be controlled.
2. Pulp and paper industry:
Knife gate valves are used in the pulp and paper industry for controlling the flow of pulp, paper stock, and other fluids. They are often used in applications where high consistency and abrasive materials need to be controlled.
3. Mining:
Knife gate valves are used in mining operations for controlling the flow of slurry, tailings, and other fluids in pipelines, pumps, and other equipment. They are often used for abrasive and corrosive materials.
4. Power generation:
Knife gate valves are used in power plants for controlling the flow of ash, coal, and other materials in pipelines and other equipment. They are often used in applications where high temperatures and abrasive materials need to be controlled.
5. Chemical processing:
Knife gate valves are used in chemical processing plants for controlling the flow of corrosive and abrasive fluids in pipelines, reactors, and other equipment. They are often used in applications requiring tight shut-off and high durability.
Overall, knife gate valves are well-suited for applications where a tight shut-off is required and abrasive and corrosive materials must be controlled. They are widely used in many industrial processes and are essential to pipelines, pumps, and other equipment.
