* Notes for Body Minimum Friction Loss Chart:
Minimum inlet pressure is 10 psi higher than set point or the additional body friction loss at intended flow, whichever is higher.
(friction loss may be important at flows above 20 ft/s)
Example: A 6” valve intended to flow 2000 GPM at 150 psi has a friction loss of 20 psi at 2000 GPM. The minimum inlet pres-
sure would be 150 + 20 = 170 psi. When inlet pressure is below set point, the outlet pressure will be the pressure at the inlet
minus the friction loss.
