APPLICATION
Control ball valves provide predictable and accurate control of flow rates in the pipeline, where the valve is mount- ed. The flow rate is controlled by means of a lever with a scale and flow rate control with linear relation. Special design of the ball with a figured groove allows to reduce noise and to increase control accuracy. The valve is installed on the pipeline according to the arrow specifying the direction of the working media.
