The sprinkler shall be capable of accepting all 570 Series spray, stream, flood, and microspray nozzles and male-threaded risers and extenders. The sprinkler shall operate within a 2075 psi (1,45,2 Bar) pressure range. The sprinkler shall have an in-riser pressure regulator that maintains constant 30 psi (2,5 Bar) outlet pressure to eliminate misting and fogging caused by pressures above 30 psi (2,5 Bar). The sprinkler shall have a high-flow shut-off device built into the riser that restricts water loss if the nozzle is removed or damaged, eliminating potential erosion or safety issues. The shut-off device shall allow for nozzle and filter replacement or maintenance while the system is running. The body of the sprinkler shall be injection molded from ABS, a noncorrosive, impact-resistant, UV-resistant, heavy-duty plastic material. The sprinkler shall have a color-coded riser screen filter, stainless steel or plastic, appropriately sized to prevent entry of foreign material to the nozzle. All parts shall be removable through the top of the sprinkler case. The sprinkler shall have a single-piece riser/body seal, that flushes only upon retraction to clear any debris from around the riser, and a stainless-steel spring to ensure positive retraction. The seal shall have no flush during pop-up to allow the maximum number of sprinklers per station. The seal shall be a single piece injection molded from Alcryn§, a synthetic rubber.
