How to use the selection chart
The curves labeled 2, 3, 4, 5, etc. represent upstream pressure, and the vertical line on the left side of the figure represents downstream pressure.
Example description
The pressure reducing valve requires a flow rate of 120 kg/h, with the pressure decreasing from 8 barg to 6 barg. Moving horizontally to the right along the downstream pressure (6 barg) curve shown on the left side of the diagram, until it intersects with the upstream pressure (8 barg) curve, and then vertically downwards along the intersection point, it can be seen that SRV2S meets the requirements.
