Product Description

The patented design of Senninger's PSR-2 is ideal for surface water and in pivot operations. These can handle flows from 0.5 to 15 GPM. As with all Senninger pressure regulators, the PSR-2 will maintain a constant preset outlet pressure with various inlet pressures, thus keeping applicators coverage area uniform. 

Please Note: The pressure regulator shall maintain the predetermined operating pressure provided that the inlet pressure is at least 5 PSI above the expected outlet pressure, but not exceeding the maximum inlet pressure.


  • 100% pressure tested to ensure quality and performance
  • Very low hysteresis and friction loss
  • Manufacturer Warranty: 2 Year workmanship, materials and performance
  • Recommended for outdoor use only, not NSF certified
Please note: Irrigation pressure regulators need outflow and back pressure to regulate the pressure within your irrigation system. With no water flowing through the regulator, the inlet and outlet pressures will measure the same. To verify the pressure maintained in your system, you will need to place a pressure gauge at the end of one of zones, turn the zone on, let it pressurize and once the lines have filled and emitters begin to flow then take the reading. This will reflect the working pressure within your system.
Special note: This pressure regulator is not designed to operate under static (constant) pressure. It must be installed after any valves or timers to operate correctly. Using this item under static pressure will eventually weaken the internal spring and cause the regulator to fail.
