plug valve Features

--------------------------------------------------------------------------------

The simplest and most common general type of http://www.corrosion-resistant-valves.com/corrosion-resistant-pipe-fitting.html is a 2-port valve, which has two positions, open to allow flow, and shut (closed) to stop flow. 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 this kind of plug valve a quarter-turn valve. There is often a mechanism limiting motion of the handle to a quarter turn, but not in glass stopcocks.Features : 1) Size Range : 25 mm to 150 mm 2) Flange Dimension : ANSI B16.5 3) Face to Face : ANSI B16.10 4) Lining Thickness : Min. 3.0mm/4.0mm 5) Spark Test : Body liners & all wetted parts are spark tested at 20,000 Volts
