In-line Components, Including Straight-through Valves

The number plotted in a box next to each component corresponds to the number of the item in the material list. All Valves and other in-line components have a flow-direction arrow plotted alongside (unless the arrows have been suppressed using the FLOWARROWS command). See the Valve with flow arrow image.

The directions of Valve operating spindles are correctly indicated. Valve operating spindles that are skewed will be plotted in the nearest primary direction and a comment giving the actual direction added, as shown in the Valve with flow arrow and direction text for spindle image.

If Valve tag numbers have been stored in the DESIGN database as names, they can be included in the boxed enclosures below the material list numbers if they are switched on using the TAGGING command. See the Valve with tag number image.
