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:

All Rain Bird pressure regulating spray bodies are WaterSense certified by ICC-ES

PATENTED PRS pressure regulator built into stem. No parts to be installed at the site. 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

1800 SAM-PRS-30 and SAM-PRS-45 Series

Combines Seal-A-Matic check valve and PRS-30 or PRS-45 for best performance

Ideal for sloped applications that have fluctuating or high pressure
