Operation in shaded areas not recommended.
Flow in this area is outside the operating
parameters of the valve
Flow in this area is outside
the operating parameters of
the valve
To find the maximum flow rate that this valve can control to, you need to know P1 (inlet pressure), P2 (outlet pressure set point), and maxi-
mum flow in SCFH.
1. Select the Range row that encompasses your outlet Set Pressure (P2). 3. Select the column that best represents your Inlet Pressure (P1).
2. Select the sub-row that is closest to your actual outlet Set Pressure (P2) 4. The maximum flow rate that the valve can regulate is the number represented at the
intersection of the sub row and the Inlet Pressure column.
