Design Details: A butterfly valve is a valve which can be used for
isolating or regulating flow. The closing mechanism takes the form
of a disk. Operation is similar to that of a ball valve (quarter
turn) which allows for quick shut off. Butterfly valves are
generally favoured because they are lower in cost to other valve
designs as well as being lighter in weight, meaning less support is
required. The disc is positioned in the centre of the pipe, passing
through the disc is a rod connected to an actuator on the outside
of the valve. Rotating the actuator turns the disc either parallel
or perpendicular to the flow. Unlike a ball valve, the disc is
always present within the flow, therefore a pressure drop is always
induced in the flow, regardless of valve position. The valve may
also be opened incrementally to throttle flow.
