KOBOLD NAD-AC brass-needle valves allow economical regulation of the flow volume of liquids and gases. 

The amount of flow change is determined by the size of the resulting angular gap between the cone and seat. The flow is regulated by a cone-shaped valve that is moved by means of a spindle away from or toward the valve seat. 

The rate of flow change is determined by how much the valve spindle is turned as well as the pitch of the valve spindle thread.
