Nominal Size Selection Chart - Yoshitake GP-2000 Installation & Operation Manual

5.4 Nominal size selection chart

For example, take a pressure reducing valve whose inlet pressure (P ) is 0.6 MPa, reduced
1
pressure (P ) 0.4 MPa, flow rate 600 kg/h. When determining the nominal size, find the point of
2
intersection (A) of inlet pressure 0.6 MPa and reduced pressure 0.4 MPa. Vertically proceed from
point (A) to come across the flow rate 600 kg/h, and regard this point as (B). Point (B) is
between nominal sizes 20A and 25A. Select the larger nominal size (in this example, nominal size
25A)
