Valve Type with Minimum Wire Drawing and Seat Erosion

What type of valve minimizes wire drawing and seat erosion?

a) globe valve b) gate valve c) plug valve d) hand valve e) wedge gate valve

Answer:

The valve type that minimizes wire drawing and seat erosion is the plug valve.

The valve that minimizes wire drawing and seat erosion is the plug valve. Wire drawing and seat erosion are wear phenomena which happen when there's a high velocity flow of a liquid through a valve. These can degrade the valve over time.

Plug valves are designed to combat these issues as they have a conical or cylindrical plug with one or more flat or hollowed out passageways. Other valves like the globe valve, gate valve, hand valve, or wedge gate valve are less efficient at reducing wire drawing and seat erosion compared to the plug valve. This is largely due to the design and mechanism of the plug valve, which is more conducive to reducing these wear phenomena than other types of valves.

So, if you are looking for a valve type that can withstand high velocity flow and minimize wear and tear, consider using a plug valve for your application.
