What is a butterfly valve used for?

Answer 1

A butterfly valve is from a family of valves called quarter turn valves. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is open, the disc is rotated a quarter turn so that it allows unrestricted passage. The position of the disc is effected from outside the valve. And the Steel butterfly valve is one kind of butterfly valve , the main material is steel.

Answer 2

a valve is used for regulating the flow of a fluid by opening, closing or partially obstructing a passegway

:)

The correct answer would be as followsA "valve" can be used for positive shut off such as a gate or ball valve valve

A Glove pattern valve is used for throttling and a needle valve is used fro fine adjustments such as use on oxygen and combustible lines.

Then there are check valves which in theory prevent back flow of mediums such as liquid or air

There are Leslie valves for example that are pressure reducing valves for steam stations..

For example the pressure a structure maybe as high as 125# and to make it more manageable one would use pressure reducing valves.

There is no one valve fits all applications

Answer 3

For certain high volume low pressure flow applications, butterfly valves or pneumatic controlled flapper valves are more than adequate to throttle the flow.

For high pressure and low flow control applications hydraulic blocks, balanced valves, needle valves and globe valves are preferred.

Answer 4

The butterfly valve is used to regulate the flow of fluid.that is quantity of fluid can be varied by operating this.

Answer 5

A butterfly valve is used to isolate or regulate flow in a system of pipes. Butterfly valves are usually lower in cost when compared to other types of vales, so they are usually favored.
