• Ball Valve Torque Calculation | Sciencing

    Torque The rotation of the ball requires a certain turning moment, or torque, which depends upon factors such as pressure drop and fluid flow velocity. The torque requirement of a ball valve can be calculated from its breakaway torque and dynamic torque.
