RainBird PRS-Dial Pressure Regulating Module

Description

RainBird PRS-Dial Pressure Regulating Module

Features:
• The PRS-Dial is an excellent means of regulating outlet pressure at the
valve regardless of incoming pressure fluctuations. The visible scale
makes adjustment quick and easy. The regulator fits all
Rain Bird PGA, PEB, PESB, PESB-R, EFB-CP, and BPES series valves
• Regulates and maintains constant outlet pressure between 15 and 100
psi (1.04 to 6.9 bar) within ±3 psi (±0.21 bar)
• Adjustment knob with detents permits fine-tune setting in 1⁄3 psi (0.02
bar) increments. Dial cartridge makes installation and adjustment quick,
easy and accurate 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-D 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 100 psi (6.9 bar)*
• Regulation: 15 to 100 psi (1.04 to 6.9 bar)
• Flow: Refer to chart
* While the PRS-Dial unit can withstand pressures up to 200 psi (13.8 bar), accurate pressure
regulation can be maintained only up to 100 psi (6.9 bar)
Model
• PRS-D
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 pressure
regulating master valve or inline pressure regulator is required
• 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 (2.29 m/s)
• 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
