    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.

    For example:

    (1) For corrosive media, such as chloride, acid and alkali, usually choose stainless steel or PVC material knife gate valve;

    (2) For high temperature, high pressure and high wear resistance requirements of the medium, usually choose steel or nickel-based alloy processed knife gate valve;

    (3) For industrial gypsum, cement powder and other equipment atmosphere transport medium, usually choose ductile iron knife gate valve.
