How to use the chart
Each chart shows flow characteristics
at Cv = 1.
To find a flow rate at each size,
multiply the value you find in the chart
by each Cv value shown in page 2.
The chart for air shows the flow
characteristics obtained at the fluid
temperature of 20°C.
<Example>
Model: MD-53,
Nominal size: 20A,
Inlet pressure: 0.6 MPa
Outlet pressure: 0.5 MPa
The air flow rate at the conditions
above can be obtained by the
following formula.
1000 L/min (standard condition) [Find
the value by using the chart for air] x
16 (Cv value) = 16000 L/min
(standard condition)
