ΔP: Differential pressure MPa
[How to use the chart]
When selecting the nominal size of a solenoid valve whose inlet pressure (P
), outlet pressure (P
) and

2
flow rate (V) are 0.6 MPa, 0.3 MPa and 200 L/min, respectively, first find intersection point (A) of the
differential pressure before and after the valve [ ∆ P = 0.6-0.3 = 0.3 MPa] and V = 200 L/min. Since this
intersection point (A) lies between nominal sizes 20A and 25A, select the larger one, 25A.
