A mini ball valve is a compact, quarter-turn (90-degree rotation) valve used to control the flow of liquids or gases. It uses a rotating ball with a bore (hole) through its center to either allow flow (when aligned with the pipe) or stop flow (when perpendicular to the pipe).
The defining characteristic is its small size and reduced port (the internal diameter is smaller than the pipe's outer diameter, but it's now common in industrial sizes). This makes them ideal for applications where space is tight and low flow is acceptable.
Mini ball valve can be used under 25 kg pressure, can be widely used in purification equipment cooling equipment and other through the medium is gas or water or diesel under a variety of machines and equipment, application scenarios.
