    Tips: What sizes are knife gate valves available in?

    Knife gate valves are available in a wide range of sizes, typically ranging from 2 inches to 60 inches in diameter. The size of a knife gate valve is determined by the diameter of the pipeline it is intended to be used with. The size of the valve should match the size of the pipeline to ensure proper flow control and a secure fit.

    It's important to note that the actual dimensions of a knife gate valve can vary depending on the manufacturer and the specific model. Some manufacturers offer custom sizes to accommodate unique pipeline requirements. Additionally, some knife gate valves are designed for specific applications, such as slurry control or high-pressure applications, and these may have different size ranges or specifications.
