Nominal Size Selection Chart - Yoshitake AL-27 Product Manual

The flow rate of each size with 25% of accumulation (excess to the set pressure) is shown in Figure 3.
See Figure 4 when the accumulation is less than 25%.
Example:
When selecting the nominal size for opening pressure of 0.3 MPa and discharge capacity of
3
1.0 m /h, find the intersection point (a) of the opening pressure of 0.3 MPa and the discharge
capacity of 1.0 m
select the larger one, 20A.
