  • The co-molded, pressure activated, Triple-Blade Wiper Seal assures positive seal without excess “flow-by” which enables more heads to be installed on the same valve. A base seal provides a positive seal during operation and Triple-Blade Wiper Seal serve to precisely balance flushing, flow-by, and debris protection to optimize performance and durability during pop-up. Precision controlled flush at pop-down clears debris from the unit, ensuring positive stem retraction in all soil types.
  • Debris pockets in the base of the spray body collect debris and prevent recirculation in the body during operation reducing wear.
  • Designed for use with all Rain Bird plastic spray head nozzles – Rotary Nozzles, U-Series, MPR, HE-VAN, VAN, and SQ Series.
  • Parts developed to be resistant to corrosion in treated recycled water containing chlorine and other chemicals.
  • Strong stainless steel spring provides reliable stem retraction and withstands corrosion.
  • Patented PRS pressure regulator built into the stem. No parts to be installed at the site. Saves time and money.
  • Maintains constant outlet pressure at 45 psi (3;1 Bars). Spray heads and nozzles perform best at 45 psi. Ensures maximum spray head and nozzle performance; even with varying inlet pressures. Maintains constant pressure regardless of nozzle used.
  • Reinforced ratchet mechanism on all models allows easy nozzle pattern alignment without tools, withstands chemicals in recycled water, and prevents pattern misalignment over time.
  • Pre-installed 1800 Pop-Top™ flush plug blocks debris from entering after flushing and allows for easy nozzle installation.
  • Constructed of time-proven UV-resistant plastic and corrosion resistant stainless steel parts, assuring long product life.
