5.1 Nominal size selection chart
For air
[How to use the chart]
When selecting the nominal size of a solenoid valve whose inlet pressure (P
(20˚C) flow rate (Q) are 0.5 MPa, 0.3 MPa and 600 m
intersection point (A) of P
(A) to find intersection point (B) with Q = 600 m
lies between nominal sizes 20 A and 25A, select the larger one, 25A.
