Rain Bird - 4" Pop-Up Adjustable Part Circle Rotor with PRS Pressure Regulation

4" 5000 Series Part-Circle Pattern Pop-up Rotor with PRS Pressure Regulation is ideal for medium to large-size lawns and evenly distributes water from 25' - 50'.

• Superior Distribution Uniformity - 5000 Series Rotors with Rain Curtain Technology are engineered to deliver a uniform spray pattern, giving you a consistently green lawn throughout.
• Superior Wind Resistance - The larger water droplets produced by Rain Curtain technology prevent misting and airborne evaporation so the right amount of water is delivered to the right place, saving you water and money.
• Superior Close-in Watering - Gentle close-in watering eliminates dry spots around the rotor, prevents seed washout and allows the turf to grow healthy with no matting or bending.

Additional Features:

• In-stem pressure regulator (PRS) reduces operating pressure to 45 PSI for optimal nozzle performance
• PRS saves water by:
  • Eliminating head-to-head pressure variations
  • Eliminating misting due to high pressure
  • Improving nozzle distribution uniformity by operating the nozzle at optimum pressure
• Maintenance-free design can be easily retrofitted into existing 5000/5000 Plus, T-Bird and Hunter® PGP (using UPG model) rotor cases without digging up the entire body
• Pressure: 25-75 PSI 
• Faster maintenance with a new self-cleaning arc adjustment screw
• Heavy-duty cover assembly for extra durability
• Rain Curtain Nozzles
• Slip clutch mechanism for quick adjustment on installation
• Heavy-duty retract spring assures positive pop-down
• Top-adjust arc adjustment requiring only a flat-blade screwdriver
• 40 - 360° arc rotation and reversing full circle rotation in one
• Radius adjustment screw allows up to 25% radius reduction without changing nozzles
• Pressure-activated multi-function wiper seal protects internals from debris and assures positive pop-up and retraction
• Reinforced flow path for additional side load strength
• Additional O-rings and seals for extra protection in "gritty" water
• Pressure Regulating Stem (PRS) which regulates pressure at the head, assuring optimum performance
