Hunter Institutional Spray sprinkler bodies with 1/2" inlet; accepts all female threaded nozzles
*Other sizes available upon request*
For long pipe runs with wide variations in available pressure, large elevation changes that make design difficult, or high and variable pressure situations that create nozzle performance problems, the Institutional Spray provides a comprehensive solution. Built-in pressure regulation to a true 30 PSI. You’ll get controlled, reliable pressure to Hunter’s wide array of available nozzles, as well as the elimination of misting, fogging or unwanted variation.
The pressure regulator is also dirt tolerant, handles extreme operating pressures up to 100 PSI, and will control flow rates by 70% if the nozzle is damaged or removed. Best of all, unlike pressure compensating screens, this regulator is built into the sprinkler, so it’s ready from the get-go to handle the extremes your site dishes out.
