butterfly valves can be used in many industries
When it comes to valves, there are a lot of types that can be used in different ways. One particular type of valve would be the butterfly valve. This valve is specifically used in large pipes, and is described as a disk rotating on a diametrical axis inside a pipe, also used as a throttle valve or a damper. The BUTTERFLY VALVE is a sort of device that controls the flow, normally used to administer a certain fluid that would flow through a certain section of a pipe. This valve is similar (with regards to operation) to a ball valve. The BUTTERFLY VALVE, having a flat circular plate, is positioned in the center of the pipe, and the plate has a rod through it that is attached to a handle on the outside of the valve. This valve works by rotating the handle, and turning the plate over either in a parallel position, or perpendicular to the flow. Not like tthe ball valve the plate in the butterfly valve is always there within the flow; therefore a kind of pressure drop is always induced in the flow, despite the position of the valve.
Butterfly valves have three different types. The high performance butterfly valve , which is generally double eccentric in design, is working the pressure for up to 725 PSI. The second type would be the resilient butterfly valve, which has a flexible rubber seat. This type would work the pressure for up to 232 PSI. And finally, the last type would be the tricentric butterfly valve, which is normally designed with metal seating. This valve works the pressure for up to 1450 PSI.
