<How to use the chart>
When selecting the nominal size of a temperature regulator whose inlet pressure, outlet pressure, and
flow rate are 0.3 MPa, 0.15 MPa, and 1 m
3
/h, respectively, first find intersection point (a) of the
differential pressure (
Δ
P) of 0.15 MPa (0.3 MPa – 0.15 MPa) before and after the valve and the flow rate
of 1 m
3
/h. Since this intersection point (a) lies between nominal sizes 15A and 20A, select the larger one,
20A.
* Chart of the flow rate is a reference value.
