Rain Bird PRS-Dial Pressure Regulator for Rain Bird Valves

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, GB-R, EFB-CP-R, BPE and BPES series valves.

  • 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.
  • Three-year trade warranty.

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.
  • Pressure: Up to 100 psi (6.9 bar)
  • Pressure Regulation: 15 to 100 psi (1,0 to 6,9 bar)
  • Accuracy: +/- 3 psi (+/- 0,2 bar)
  • Flow: refer to charts
  • Temperature: up to 150 F (66 C)

I have too high pressure for some of my sprinklers

I have too high pressure for some of my sprinklers
Robert W on Feb 18, 2019
All of my valves and sprinklers have very high pressure. Can I install this on my sprinkler line to reduce pressure before it hits all my valves? Is this the right type of pressure regulator or do i use an inline pressure regulator?
A shopper on Dec 20, 2014
BEST ANSWER: This regulator is for specific sprinkler valves only. it cannot be used to regulate pressure of the incoming line before the valves. Based on your question, you need an in-line regulator like the DIG P40-075. Hope this answers your question.
Will the regulator work with a Champion 3/4 inch automatic sprinkler valve?
Rich Z on May 29, 2020
BEST ANSWER: I believe the champion valves have a different size and pitch thread versus the rainbird valve, so no it will only work with a Rainbird valve.
Will this work for commercial system with 1 1/2" valves?
A shopper on Oct 3, 2015
BEST ANSWER: The simple answer is yes. This can be adapted to work with just about any size valve. However, reducing the water flow from a 1 1/2" valve through a 3/4" regulator will adversely affect the volume of water being delivered to the zone. It all comes down to calculating the required water vloume (Flow rate) for the number of heads after the regulator.
is it easy to install, and does is reduce water pressure?
Pauls S on Jun 18, 2011
BEST ANSWER: Yes, they can be adapted to any sprinkler system. I just may take creativity depending on your current setup. And yes, it does reduce pressure. I have 90 lbs from the city and at my sprinkler riser I now get 40 lbs after the install of the regulator.
