A Butterfly valve is a valve which can be used for isolating or regulating flow.There are different kinds of butterfly valves, each adapted for different pressures and different usage.
In the pharmaceutical, chemical and food industry a valve used to interrupt product flow (solid, liquid, gas) within the process. The valves utilized in these industries are typically manufactured, according cGMP guidelines (current good manufacturing practice). Butterfly valves generally replaced ball valves in several industries particularly petroleum due to the lower value and simple installation, however, pipelines containing butterfly valves can’t be ‘pigged’ for cleaning.
