8 inch Wafer Check Valve, that is, butterfly valve check valve, is a commonly used device to prevent fluid backflow and is used in various pipeline systems. It ensures that the fluid in the pipeline can only flow in one direction by setting a half-moon check valve plate, and it will be closed immediately when it is in the opposite direction. Due to its special butterfly valve shape design, Wafer Check Valve has good sealing and flow characteristics, and is simple in structure, flexible in opening and closing, and easy to install and maintain. Common materials include carbon steel, stainless steel, cast iron, copper, etc., and can be applied to fluids of various media, such as water, oil, gas, etc. At the same time, 8 Wafer Check Valve can choose different specifications and types according to different applications, such as one-way, two-way, straight-through, etc., to meet the needs of the pipeline system.
