Butterfly Valves are commonly used in applications that require isolation or flow control of liquids, gases and even some solid particles as part of a pipeline. These Industries can include Petroleum, Oil & Gas, Water, Wastewater, Chemical, Power, HVAC & Pharmaceutical. Allowing for a quick shut off, these types of butterfly valves are now commonly being used in place or as an alternative to Ball Valves. This is due to the generally lower cost, weight and installation difficulties that can come with larger sized Ball style with Butterfly requiring less space and support in the pipeline.
