A Ball valve is designed for high pressure use cases. It involves a perforated quarter-turn ball to regulate or ensure complete isolation of fluids in a pipe.

We can find them in hydrocarbons transmission pipelines or hydroelectric power plants at the bottom of penstocks (while upstream valve is a valve=butterfly one).

You can complete their description in OSM with actuator=*, turn_to_close=* or handle=*. See examples below.

Ball penstock valve	Switzerland	pipeline=valve valve=ball actuator=hydraulic_cylinder handle=no sensor:position=mechanical remotely_controllable=yes	Hydroelectric power plants usually got valves at bottom of their penstocks carrying water down to turbines due to the heavy water pressure. Such a valve is mainly fully opened or fully closed depending of the plant operational status. It is located next to a pelton turbine at the end of the penstock. Here is how a ball valve closes :

Only its head is visible from the ground surface.
