Torque required to open valve

I'm trying to calculate torque for opening typical Ball Valve. I have tried to do that using SolidWorks Motion Simulation. But, nature of graph is not valid, (i.e. Torque at start is lower and end i larger) So, can anyone help me to achieve accurate results / graph? Can this be achieved using Flow Simulation???
