Example of valve selection according to the diagram
• Find the intersection (C) of the differential pressure (A) and desired flow (B) lines. Select the dimension above point (C). For this example, size 150A should be selected.
* The speed of movement of the liquid through the pipeline should not exceed 3 m / s.
