Butterfly valve is a very common and popular flow control and regulation solution. The biggest advantages are quite simple designs and easy operation as well as long life and competitive price. This type of valve is common for such processes as Water service, Gas operation, Chemical and Petrochemical, Mining, LNG and many others. For different services there are Concentric soft seated butterfly valves, double offset and triple offset high performance butterfly valves, Top-entry butterfly valves and fully PTFE/PFA lined butterfly valves. Possible operation is a manual lever, gearbox with handwheel, pneumatic actuator and electric actuator.
