Abstract

Butterfly valves are common piping components installed to regulate flows in a wide variety of applications. Butterfly valves are compact and light-weight relative to other valve types of comparable size. They have a simple action and as a result are easily combined with actuators. In a fully open position, butterfly valves provide relatively high flow capacities with relatively low resistance to the flow. However, a source of concern in the application and control of butterfly valves are large fluid dynamic torque fluctuations and related torque reversals with the valve disk in the fully open position. Results are presented indicating that the operating characteristics of butterfly valves can be highly unsteady for certain operating conditions.
