How Stainless Steel Ball Valves Work
They also don't rust, which is a plus. When metal meets liquids, rust is likely to form, which can lead to structural weakness over time. Stainless steel is resistant to rust, meaning these valves can have a long life span without requiring replacement. This makes them a very good candidate for a number of systems.
Stainless steel ball valves operated through a spherical obstructor with a hole through it is a ball valve. When the valve is open, the ball is lifted so the hole is in the same axis as the liquid flow. When valve closes, the ball rotates and the hole is blocked; the flow stops.
