2980. Paradox control : It is an automatic mechanical follow-up valve that controls water pressure to ensure positive positioning of a needle (closing member). This control is arranged to cause the needle (closing member) to follow the movement of the control device (stand hand wheel) and to automatically maintain the needle (closing member) in the position set by the control device (stand hand wheel). A position indicator is provided in the control stand to give the operator the exact needle position. This control system makes it possible to move the needle hydraulically throughout the extreme ranges of travel without requiring the presence of water in the conduits. It also makes the routine inspection and scale-removal operations much easier to perform (illustrated).
