Ball Valve
A multi-ported, nonlubricated valve designed to provide straight through flow or ability to direct a number of flows or pressure through a single valve. The flow is controlled by the rotation of a ported ball within a suitable ported seat(s). The ball is usually engaged by a stem. It is normally operated in an open or closed position. Excludes valve, check.
