In vacuum tanks, stainless steel float balls act as the primary shutoff mechanism for vacuum pumps. As the liquid or sludge level rises inside the tank, the float ball triggers the shutoff valve, preventing liquid from entering and damaging the vacuum pump. Their durability and corrosion resistance make them ideal for this critical function.
