The Taper Plug valve is manufactured in sizes 1/2 inch thru 12 inch and is used on a wide variety of liquid,gaseous, and slurry services.
The taperd plug is held firmly into its tapered seat but can be so adjusted that complet leadk tightness is achieved together with smooth valve operation.
The tapered seat surfaces of the plug and body are not exposed to the line fluid when the valve is in the open position,
so that the effects of corrosion and erosion are confined to the less important parts of the valve.
Also since there is a straight flowpath through the valve,there is very little resistance to flow and pressure loss is minimized.
