Element: Valve.
Text: A two-dimensional valve.
Description: A Valve is a two-dimensional drawing element that draws a valve with an optional display of a value (which represents how much open the valve is). Interaction includes positioning and changing the displayed value.
Continuous valve connecting two pipes and three other types
of valves.
