1.2 Nominal size selection

<For Air>
Nominal size selection chart
[Example]
When selecting the nominal size of a pressure reducing valve whose inlet pressure (P
pressure (P ), and flow rate are 0.3 MPa, 0.2 MPa, and 200 m
2
respectively, first find intersection point (A) of the inlet pressure (P
pressure (P ) of 0.2MPa.
2
Trace down vertically from the intersection point to find intersection point (B) with the flow rate of
3
200 m /h (standard condition). Since intersection point (B) lies between nominal size 25A and
32A, select the larger one, 32A.
