Ball valve. Ball valves use a stainless steel ball to control water flow. There are three basic valve styles, making this a classic case of good, better and best (described in order as follows). All three can be used for water, oil or airflow control if the casting has WOG stamped on it. Stop valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff valves for fixtures such as sinks and toilets and outdoor sillcocks.
