Orbit Professional Series 4 in. H Twin Quarter-Circle Pop-Up Spray Head

The professional series spray head is the premium offering in the Orbit irrigation sprinkler lineup. This pop-up spray head features a highly innovative pressure regulator which you can adjust from the bottom of the can before installation, or from the top of the can after installation, from 30 to 40 PSI. 30 PSI is recommended for spray nozzles while 40 PSI is recommended for multi-stream rotator nozzles. It is available in 2-, 3-, and 4-in. riser stem heights and is ideal for a broad range of landscape types. The wiper seal features an over-molded structural support that ensures long-term, smooth retraction and prevents water from blowing by the riser stem. The riser spring which creates the pop-up action is made of corrosion-resistant stainless steel for years of reliable operation. A ratchet mechanism in the riser stem allows you to adjust the direction of the spray after installation. The bottom of the can has an integral silt trap. The spray body inlet has a standard 1/2-in. female pipe threads (FPT) which connect to Blu-Lock and Riser-Flex fittings, as well as 1/2-in. Schedule 80 PVC and cut-off risers. The brass spray nozzle features precision-machining which means that the spray is extremely uniform with high durability. The half and quarter pattern nozzles feature twin-spray technology. The all-brass spray nozzle includes a filter and adjustment screw which allows you to reduce the spray pattern down to 75 percent of its rated distance. Its low-angle trajectory helps improve efficiency by minimizing wind drift. For outdoor irrigation use with cold water only.
