Brass Ball Valve

Brass ball valves are used for shut-off applications because they provide a perfect seal even if they have not been used for long periods of time. They are generally not used in throttling applications because spherical discs do not allow for fine control. Because the actuator has to move only a short distance to open or close the valve, small adjustments and minor movements are difficult to control. Brass ball valves are used by industries that transport water or other liquids as well as gases and some solid-liquid mixtures.
