What is the purpose of a waste valve?

This valve is called the stop and waste valve because when it is in the off position it stops the water entering your sprinkler system, and opens a hole on the sprinkler side of the valve that “wastes the water” or rather, lets any water left in the irrigation pipe drain out.

What is maximum velocity ?

Terminal velocity is the maximum velocity attainable by an object as it falls through a fluid. It occurs when the sum of the drag force and the buoyancy is equal to the downward force of gravity acting on the object. Since the net force on the object is zero, the object has zero acceleration.
