  • Exclusive co-molded; pressure-activated; multi-functional wiper seal assures positive seal without excess “flow-by” which enables more heads to be installed on the same valve.
  • Precision controlled flush at pop-down clears debris from unit; assuring positive stem retraction in all soil types.
  • Strong stainless steel spring provides reliable stem retraction.
  • Ratchet mechanism on all models allows easy nozzle pattern alignment without tools.
  • Pre-installed 1800 Pop-Top™ flush plug blocks debris from entering after flushing. Allows for easy nozzle installation.
  • Constructed of time-proven UV-resistant plastic and corrosion resistant stainless steel parts; assuring long product life.
  • All sprinkler components are removable from the top without special tools; providing for quick and easy flushing and maintenance of the sprinkler.
  • Side and bottom inlets featured on 1806 and 1812 models
  • 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 30 psi (2;1 Bars). Spray heads and nozzles perform best at 30 psi. Ensures maximum spray head and nozzle performance; even with varying inlet pressures. Maintains constant pressure regardless of nozzle used.
  • Restricts water loss by up to 70% if nozzle is removed or damaged. Saves water and money. Reduces possibility of accidents and property damage. Recommended for vandal prone areas.
  • Ends misting and fogging caused by high pressure. Stops water waste. Ensures necessary watering occurs in high pressure or wind conditions.
  • Designed for use with all Rain Bird plastic and brass spray head nozzles.
  • Built-in Seal-A-Matic™ (SAM) check valve. Eliminates the need for under-the-head check valves. No parts to be installed at the site.
  • Traps water in lateral pipes in elevation changes of up to 8 feet (2;4 m). Reduces wear on system components by minimizing
    water hammer during start-up.
  • Prevents drainage from spray heads at lower elevations. Stops water waste. Ends landscape damage due to flooding and/or erosion.
  • Even stronger retract spring to accommodate elevation changes up to 8 feet (2;4 m). One of the strongest springs in the industry.
