Features

Ensure high uniformity and even flow throughout your system and eliminate the effects of pressure variations due to uneven topography or friction loss.

  • Reduces a high inlet pressure to a constant outlet pressure.
  • Ideal for use with 1/2" Acme threaded Rotator Sprinklers.
  • 0.15-5 gpm (34-1135 lph)

Choose from the following nominal regulated pressures:

  • 20 psi (1.4 bar) / 30 psi (2.1 bar) / 35 psi (2.4 bar) / 40 psi (2.8 bar) / 45 psi (3.1 bar) / 50 psi (3.4 bar) / 60 psi (4.1 bar)

Always maintain an inlet pressure of at least 5 psi more than the nominal pressure rating.
