Pressure Loss
Notes:
1. Loss values are with flow control fully open.
2. PRS-D module recommended for all flow ranges
Recommendations:
1. Rain Bird recommends flow rates in the supply line not to
exceed 7.5 ft/sec (2,29 m/s) in order to reduce the effects
of water hammer.
2. For flows below 5 gpm (1,14 m3/h; 0,32 l/s),
Rain Bird recommends use of upstream filtration to prevent
debris from collecting below the diaphragm.
3. For flows below 10 gpm (2,27 m3/h; 0,63l/s), Rain Bird
recommends the flow control stem be turned down two full
turns from the fully open position
