The professional series spray head is the premium offering in Orbit’s lineup. This version 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, to 30 or 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-, 4-, 6- and 12-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 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 flush cap allows you to blow debris out of the line before installing the nozzle (sold separately). The riser stem is compatible with all female-thread nozzles from Orbit, Hydro-Rain, and other major brands. For outdoor irrigation use with cold water only.
