Torque is an essential parameter in the design of rotary valves such as butterfly valves, ball valves, plug valves, etc. It plays an important role in the actuator selection in the case of motor-operated valves. Hydrodynamic torque or simply dynamic torque has a significant share of the total torque the valve shaft has to undergo during valve operation. Understanding the effect of dynamic torque and its variation with the opening percentage of the valve can give designers a better insight into crucial design improvements for torque reduction in their valve design.

Autonomous Valve CFD (AVC) is a CFD application that runs from your web browser. It predicts the performance of control valves using fluid flow simulations. The app predicts the coefficient of hydrodynamic torque for all the opening percentages for your control valve design and generates a curve illustrating the nature of variation of the torque coefficient.

The webinar helps you understand the importance of the coefficient of hydrodynamic for control valve designing and actuator sizing. It also covers how simulationHub helps in predicting and analyzing the hydrodynamic torque in different types of rotary valves.
