PRS-D module is recommended for use only
at flow rates in the shaded area. Loss values are with
flow control fully open.

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 (1,14m3/h; 19,2 l/m), 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; 37,8 l/m), Rain Bird recommends the flow control stem be turned down two full turns from the fully open position.
