The flow rate characteristics listed in the AR series catalog are for when the inlet pressure is 0.7 MPa, but what happens to the flow rate characteristics when the inlet pressure is 0.5 MPa?

If the IN side pressure is not 0.7 MPa, correct the flow rate with the absolute pressure ratio before use using the following formula.
absolute pressure ratio = (actual IN side pressure) / (IN side pressure in the characteristics graph)
If the IN side pressure is 0.5 MPa, it can be corrected as follows. (0.5 + 0.1) / (0.7 + 0.1) = 0.75 (the flow rate in the graph x 0.75)
The flow rate characteristics of the AR-A series can be found here.
And the flow characteristics of the AR-B series can be found here.
