Ports are openings in the valve body through which fluid can enter or leave. The plug in this kind of valve has one passageway going through it. The ports are typically at opposite ends of the body; therefore, the plug is rotated a fourth of a full turn to change from open to shut positions. This makes </ins>this <ins style="font-weight: bold; text-decoration: none;">kind of plug valve a quarter-turn valve. There is often a mechanism limiting motion of </ins>the <ins style="font-weight: bold; text-decoration: none;">handle to a quarter turn, but not in glass stopcocks.</ins></div></td></tr> <tr><td class="diff-marker" data-marker="−"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #ffe49c; vertical-align: top; white-space: pre-wrap;"><div><del style="font-weight: bold; text-decoration: none;">This page </del>is <del style="font-weight: bold; text-decoration: none;">still empty</del>. <del style="font-weight: bold; text-decoration: none;">If you know something about this product</del>, <del style="font-weight: bold; text-decoration: none;">please share your knowledge </del>with <del style="font-weight: bold; text-decoration: none;">others</del>.</div></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">Slightly conically</ins>-<ins style="font-weight: bold; text-decoration: none;">tapered metal (often brass) plug valves are often used as simple shut</ins>-<ins style="font-weight: bold; text-decoration: none;">off valves in household natural gas lines.It is also possible for a plug valve to have more than two ports. In a 3</ins>-<ins style="font-weight: bold; text-decoration: none;">way plug valve, flow from one port could be directed to either the second or third port. A 3</ins>-<ins style="font-weight: bold; text-decoration: none;">way plug valve could also be designed to shift flow between ports 1 and 2, 2 and 3, or 1 and 3, and possibly even connect all three ports together. The flow</ins>-<ins style="font-weight: bold; text-decoration: none;">directing possibilities in multi</ins>-<ins style="font-weight: bold; text-decoration: none;">port plug valves are similar to the possibilities in corresponding multi</ins>-<ins style="font-weight: bold; text-decoration: none;">port ball valves or corresponding multi</ins>-<ins style="font-weight: bold; text-decoration: none;">port valves with a rotor. An additional possibility in plug valves is the have one port on one side of the plug valve and two ports on the other side, with two diagonal and parallel fluid pathways inside the plug. In this case the plug can be rotated 180° to connect the port on the one side to either of the two ports on the other side.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">Stopcocks used in laboratory glassware are typically forms of conically</ins>-<ins style="font-weight: bold; text-decoration: none;">tapered plug valves.
