Features & Benefits
Our top-of-the-line spray, including 45 psi in-stem pressure regulation and built-in Seal-A-Matic™ check valve. Used with Rotary Nozzles, this combination improves performance and saves water
Rain Bird® 1800-SAM-P45 Series Spray Heads are ideal for use in areas with changing elevations. The built-in Seal-A-Matic™ (SAM) check valve saves water by eliminating low head drainage from spray heads located at the base of slopes or hillsides.
Trusted for over 30 years, 1800 Series Spray Heads have provided unmatched durability, reliability, and performance. Superior components and features make the 1800 Series Spray Head the spray head of choice for a wide variety of applications.
Meets the needs of spray body applications using Rotary Nozzles regardless of changing elevation or water pressures. Incorporates 1800 Series SAM feature and regulates operating pressure at 45psi (3.1 bar).
Maintains constant outlet pressure at 45psi (3.1 bar) at varying inlet pressures. Maintains constant pressure regardless of nozzle used.
Ensures maximum spray body and nozzle performance, even with varying inlet pressures.
Maintains constant pressure, regardless of nozzle used
Designed to maximize application efficiency when using Rotary Nozzles.
”SAM-PRS-45” stamped on cap for easy identification and maintenance.
Five-year trade warranty.
Matched precipitation across radius, arcs, and pattern types
Low precipitation rate reduces run-off and erosion
Adjust arc and radius without tools
A pull-up to flush feature clears the nozzle of dirt and debris
Color coded and laser marked for easy identification of R-VAN model
Maintains efficient performance at high operating pressures without misting or fogging
Compatible with all models of Rain Bird spray bodies, risers and adapters
Installing with Rain Bird 5000 MPR Series Rotors allows for matched precipitation from 8’ to 35’ (2.4m to 10.7m)
Three year trade warranty

Optional Feature Specifications:
When so indicated on the design, the 4”, 6”, or 12” high pop-up spray sprinkler shall also include a Seal-A-Matic (SAM) check valve and a 45 psi pressure regulating (P45) device. These units shall be identifiable from the top with ”SAM-PRS-45” markings on the cap.
The check valve shall prevent low-head drainage of up to 14 feet of head. The pressure regulating device shall prevent high pressure misting and undesirable performance of the nozzle stream by regulating the nozzle pressure to 45 psi for inlet pressures from 50 to 70 psi. Below 50 psi the pressure loss shall not exceed 6 psi. These models shall utilize the bottom inlet only.
½” (15/21) female threaded inlets.
