Plug Valve Design Features | Design and Engineering
The concept is simple: A rotary cylindrical or tapered plug with an opening through it is inserted into an open body to block or allow the flow of a fluid. When the plug is rotated, it permits flow through the opening and the fluid conduit; a quarter turn in either direction completely n opens or closes the valve quickly.

Gear Span Calculator | Evolvent Design
This calculator provides size measurements for gears based on measuring across a number of teeth (spanning these teeth). Rather than measuring across the entire gear, like with Measurement over Pins, span measurements use calipers to measure across a fixed number of gear teeth.As gears grow larger, the span measurement may be easier for an operator, and doesn't require giant calipers.
