Sanitary Check Valve is a valve made of imported SUS304, 316L and other materials, specially used in food, biopharmaceutical and other fields to meet the special requirements of various media in these industries. Its main function is to prevent the backflow of media in the pipeline and ensure the one-way flow of fluid, thereby protecting the safety of the system and the purity of the medium. Sanitary check valves usually have smooth, seamless, self-draining fluid channels, which are very suitable for steam and in-place cleaning needs.
