In the early morning hours of a dairy factory, pasteurized fresh milk flows through a pipe toward the filling line. When an operator presses a button, a seemingly ordinary Sanitary Valve valve on the pipe slowly opens, allowing milk to flow smoothly through. Few people notice that the inner wall of this valve is performing an invisible act of protection: its surface is so smooth that you can see your reflection in it, without a single dent or crack, making it impossible for even microorganisms to "build a home." Its material, infused with molybdenum, releases no harmful substances even when exposed to acidic, fruity milk. Its structure is designed like a "perfect piece of art," ensuring that every component can be thoroughly cleaned after disassembly, and even the threaded connections are sealed...

This is a sanitary valve—an "invisible guardian" hidden in the production chains of industries like food, medicine, and cosmetics. With meticulous attention to detail, it safeguards humanity's most fundamental need for safety.
