The PRS-Dial is an excellent means of regulating
outlet pressure at the valve regardless of incoming pressure
fluctuations. The visible scale makes installation quick and
easy. The regulator fits all Rain Bird PGA, PEB, PESB, GB,
EFB-CP, BPE and BPES series valves. The dial cartridge (sold
separately) retrofits easily into existing PRS-B units.
Application Information:
Proper operation requires inlet pressure to be a minimum
of 15 psi (1,04 bar) higher than desired outlet pressure
For areas with very high pressure or uneven terrain, install
sprinklers with PRS pressure regulating stems and/or SAM
check valves
When inlet pressure exceeds 100 psi (6,9 bar), a regulating
master valve or inline pressure regulator is suggested.
Rain Bird does not recommend using the pressure regulating
module for applications outside the recommended flow ranges.
To reduce the effects of water hammer, Rain Bird recommends
flow rates in the supply line not to exceed 7.5 ft/sec (2,3
m/s).
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.
For flows below 10 gpm (2,27 m3/h; 0,63 l/s) Rain Bird
recommends the flow control stem be turned down two full
turns from the fully open position.
Features and Benefits:
Regulates and maintains constant outlet pressure between
15 and 100 psi (1,0 to 6,9 bar) within +/- 3 psi (+/- 0,2
bar)
Adjustment knob with detents permits fine-tune setting
in 1/3 psi (0,02 bar) increments
Improved spike reduction capabilities reduce water hammer
Ergonomic design with snap-tight cover to prevent vandalism
Waterproof dial cartridge eliminates fogging and binding
Dial cartridge retrofits into all existing PRS-B units
