Built into the riser and restricts water loss by 99% if the nozzle is removed or damaged, eliminating potential erosion or safety concerns. Allows for “dry” nozzle and filter-replacement or maintenance, while the system is running.
Patented In-riser Pressure Regulator
Maintains constant 30 psi (2,1 Bar) psi outlet pressure, which minimizes misting and fogging caused by pressures above 30 psi (2,1 Bar).
Zero Flush Wiper Seal
Prevents flushing on pop-up, allowing more sprinklers on the same line.
Enhanced Retraction Spring and Wiper Seal
Robust retraction spring and enhanced seal material ensures positive pop-up and retraction on all 570Z models.
Small 2” (50mm) Diameter Cap
Less visible, reducing damage from exposure or vandals.
