PRS Dial Valve Pressure Regulator

Features

  • 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.
  • 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 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 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; 37.8 l/m) Rain Bird recommends the flow control stem be turned down two full turns from the fully open position.
