Example :
- Given Flow Rate = 63 GPM. Nominal
required pressure = 20 psi.
- Using Pressure Regulator Model 2" x 6
(6 regulating units) will result in 10.5 GPM
per regulating unit.
- 10.5 GPM per regulating unit will result in an
output pressure of 18 psi. (See Regulated
Pressure vs. Flow Rate graph).
- Head loss of Pressure Regulator 2" x 6 at
63 GPM is 5 psi. (See Head Loss vs. Flow
Rate graph).
- Design pressure at inlet of Pressure Regulator
should be 18 + 5 = 23 psi.
