Primary Application
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.
Features
- Regulates and maintains constant outlet pressure
between 15 and 100 psi (1,0 to 6,9 bars) within +/- 3 psi (+/- 0,2 bars)
- Adjustment knob with detents permits fine-tune
setting in 1/3 psi (0,02 bars) 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
- Schrader valve connects pressure hose gauge,
ordered separately
- Easy field installation. PRS-Dial threads
underneath the solenoid and adapter
- Corrosion-resistant glass-filled nylon for
rugged performance
Operating Range
- Pressure: Up to 200 psi (13,8 Bars)
- Pressure Regulation: 15 to 100 psi (1,0 to 6,9
Bars)
- Accuracy: +/- 3 psi (+/- 0,2 bars)
- Flow: refer to charts
- Temperature: up to 150 F (66 C)
Models
Application Information
- Proper operation requires inlet pressure to be a
minimum of 15 psi (1,04 bars) higher than desired outlet pressure
- For areas with very high pressure or uneven
terrain, install sprinklers with PRS pressure regulating stems or SAM check
valves
- When inlet pressure exceeds 100 psi (6,9 Bars),
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; 0,31 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.
