Abstract
A needle valve in which the needle is moved with respect to its valve seat. The distal end of the needle has a length of a constant, uniform diameter that allows the flow to reach a maximum flow and not change while that finite length is moving within the valve seat. This allows a less critical placement of a stop that prevents further movement of the needle away from its valve seat.
