valve torque. The initial ball/seat torque of the valve is results of the seats preload (determineby the designer), and the seat material. The relative high friction arias, together with the floating ball design concept,which allows the system pressure to force the ball into the downstream seat, cause the Ball/seat torque to be very sensitive to

By means of a flange type torque sensor, the torque signal is recorded when the motor is driving a constant torque load, (Fig. 1 (a)), and a ball mill, (Fig. 1 (b)). The presence of an oscillating component of around ± 2 Nm, superimposed to the average value, can be observed in the case of constant torque load.
