Nominal sizing chart (for steam)

Sizing Chart (Steam)


Example

When selecting the nominal size of the pressure reducing valve at the inlet pressure (P1), reduced pressure (P2) and steam flow, respectively, 1.3 MPa, 0.6 MPa and 200 kg/h, first find the point of intersection of the pressure lines at inlet 1, 3 MPa and reduced pressure 0.6 MPa. From this point, draw a line down from the intersection of the lines to find the nominal size with a flow rate of 200 kg/h or more.

In this case, the nominal size will be 20A.

Note. The nominal sizing diagram is built on the basis of measurement data. As you can see, there is no specific relationship between the pressure difference and the flow rate on the diagram, so it is impossible to calculate a fixed coefficient Сv.

• The safety factor should be taken equal to 80-90%.
