FLOW CALCULATIONS
The Minimum Flow is calculated from the minimum recommended pressure drop,
1 ft WG (=3.0 kPa)
The Nominal Flow is calculated from the maximum setting of the valve and the minimum recommended pressure drop,
2 ft WG (=6.0 kPa)
The Maximum Flow is calculated from the maximum setting of the valve and the maximum pressure drop,
20 ft WG (=60.0 kPa)
