Hunter PRS40 Pop-Up Sprinkler with 280kPa Pressure Regulator & Check Valve

The Hunter Pro-Spray™ PRS40 is the industry’s best-in-class spray body designed specifically to optimize the performance of MP Rotator nozzles. Equipped with a factory-installed pressure regulator set at 2.8 bar (280 kPa), the PRS40 ensures every MP Rotator operates at peak efficiency, delivering uniform multi-stream coverage with maximum water savings. By regulating pressure, the PRS40 eliminates misting and overspray, allowing water to soak evenly into the soil — reducing runoff and improving plant health.

Built with the industry’s strongest spray body, the PRS40 is engineered for years of reliable operation in both residential and commercial landscapes. Its rugged construction, chemical- and chlorine-resistant co-moulded wiper seal, and innovative cap-to-body design prevent leaks and guarantee durability even under harsh conditions. The built-in drain check valve further prevents low-head drainage on slopes, conserving water and protecting landscapes from erosion.

Whether used in new installations or retrofits, the PRS40 combines the durability of Hunter’s Pro-Spray line with the proven water efficiency of MP Rotator nozzles, making it the ultimate choice for high-performance irrigation.
