- Definition mechanical device used to release excess or unwanted liquids or gases from a storage container Reference "Wise Geek > What is a Drain Valve? http://www.wisegeek.com/what-is-a-drain-valve.htm [8.4.2013]"
- Comment The valve is usually opened by turning a screw or handle, although some drain valves are automatically opened when a set pressure or temperature is reached. When the valve is opened, liquid or air drains from the storage tank due to gravity or pressure differential.
