The Perfect Pair for Pressure Regulation

Rain Bird’s pressure-regulating stem (PRS) saves up to a gallon of water per minute.

We offer three perfectly paired combinations of PRS spray bodies and high-efficiency nozzles. Each pair is designed to work together to give you the best possible performance across your entire irrigation system — all while saving water.

All 1800s:

• Co-molded wiper seal provides unmatched resistance to grit, pressure, and the environment
• Constructed of time-proven UV-resistant plastic and corrosion-resistant stainless steel parts, ensuring long product life
• Precision-controlled flush at pop-down clears debris from the unit, assuring positive stem retraction in all soil types
• The two-piece ratchet mechanism allows easy nozzle pattern alignment and provides added durability
• Five-Year Trade Warranty

1800 SAM Series:

• Built-in Seal-A-Matic (SAM) check valve. Eliminates the need for under-the-head check valves
• Ideal for use in areas with changing elevations
• Traps water in lateral pipes in elevation changes of up to 14 feet (4.2 m), eliminating low head drainage at the base of slopes or hillsides
• Reduces wear on system components by minimizing water hammer during start-up

1800 PRS Series:

• PATENTED PRS pressure regulator built into the stem. No parts are to be installed at the site. It saves time and money
• Maintains constant outlet pressure at 30psi (2.1 bar) or 45 psi (3.1 bar) at varying inlet pressures regardless of nozzles used
• 30 psi is recommended for optimal spray nozzle performance, 45 psi is recommended for optimal rotary nozzle performance
