A ball valve is a flow control device which uses a hollow, perforated and pivoting ball to control liquid flowing through it. It is open when the ball's hole is in line with the flow inlet and closed when it is pivoted 90-degrees by the valve handle, blocking the flow. The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy …

When p <= 0, the ball hits the ground and bounces. You can model the bounce by updating the position and velocity of the ball: Reset the position to p = 0. Reset the velocity to the negative of its value just before the ball hit the ground. To account for energy loss, multiply the new velocity by a coefficient of distribution (-0.8).

Ball valves have a spherical closure unit that provides on/off control of flow. The sphere has a port (bore) through the center. When the valve is positioned such that the bore is aligned in the same direction as the pipeline, it is in the open position, and fluid can flow through it. When rotated 90°, the bore becomes perpendicular to the ...
