Meets the needs of spray body applications using Rotary Nozzles regardless of changing elevation or water pressures. Incorporates the 1800 Series SAM feature and regulates operating pressure at 45psi (3.1 bar).
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.
