Hunter - PROS-04-PRS40-CV - 4'' Pro-Spray Pop-Up Sprinkler w/ Check Valve & 40 PSI Regulated (No Nozzle)

Save 40%

Hunter designed the Pro-Spray PRS40 spray bodies to be the strongest in the industry. The rugged, extra thick ABS body and cap can withstand the harshest conditions with confidence. The PRS40 is designed for maximum efficiency when used with the MP Rotator heads. The gray capped PRS40 paired with the MP Rotator can decrease water usage by 30% or more over standard sprays. Pro-Spray PRS40 is regulated at 40 PSI to ensure optimal operation for maximum efficiency. The pop-up riser has male threads for connecting any standard spray nozzle or MP rotator with female threads inlet. This rugged Pro-Spray body is recommended for commercial and residential applications . Unit requires a dynamic pressure differential of 10 PSI in system.

The pressure-regulated Pro-Spray® PRS30 and PRS40 meet the stringent requirements established by the U.S. Environmental Protection Agency to identify products that exemplify water conservation and performance.


The industrys most rugged wiper seal is co-molded from two types of chemical and chlorine-resistant materials. This pressure activated, multi-function wiper seal reduces flow-by, operates at low pressures, and allows more sprinkler heads to be installed on the same zone. Its innovative design prevents debris from entering the seal when the riser is retracted, reducing riser stick-ups.


The Pro-Spray line incorporates a heavy-duty ribbed body and durable cap engineered to withstand the harshest environments, including the rigors of foot traffic and the abuses of heavy machinery. In addition, the buttress thread design provides superior strength in cap-to-body gripping capacity helping the head to withstand high inlet surge pressures.


The industrys strongest spring for positive retraction under any conditions.


Optional check valves eliminates drainage at heads installed on slopes, protecting landscapes from damage and erosion while reducing water waste. Choose from the convenience of factory-installed check valves or the flexibility of field installation.


In the event of a missing nozzle, FloGuard technology reduces the flow of water from the riser to a 0.5 GPM (10 tall) indicator stream, eliminating water waste and preventing landscape erosion while providing a visual indicator for repair.
