It's a known fact that rotors have been designed to operate most efficiently at entirely different water pressures than sprays. Sprays like the Hunter PS and SRS perform best at 25 psi; mid-range rotors like PGP ® and I-20 Ultra are designed for 50 psi; while larger rotors such as I-25 Plus and I-40 handle 60-70 psi. When all the different types of sprinklers you install can function at their individual optimum pressures; your system will not only enjoy the advantages of better coverage; but better system longevity as well.
So; at a commercial site – where; quite often; incoming pressure can reach levels in excess of 100 psi – what can you do to get the pressure down to a desirable level to ensure the most efficient (and safe) operation of each and every one of the different types of sprinklers you install?
Well; if you're discriminating enough to have selected Hunter sprinklers as the best choice for your installation; chances are you were also astute enough to have chosen Hunter ICV valves. And it is the ICV that offers the ideal solution for high pressure situations – all you need to do is simply be sure to include the optional Accu-Set feature when you buy these valves.
With Accu-Set on the ICV ; it is possible to regulate the pressure coming out of the valve (efficiency is guaranteed for conditions up to 200 psi) to a lower; more appropriate level for the sprinklers you install. With an easy-to-read dial that sits atop the valve; the ICV makes it exceptionally simple to select and adjust the pressure to the setting you desire (anywhere from 20 to 100 psi) and you can be certain that what you select will never waver.
Of course; since different sites have different requirements; Hunter makes the ICV in four different models. Our 1"; 1 1/2"; 2" and 3" versions all offer the Accu-Set option; providing a trio of excellent choices for larger landscapes that require flows in the .25 to 200 GPM range. Also available is ICV Filter Sentry™ ; an incredible scouring mechanism that works continuously whenever the valve is in operation; helping to keep microscopic contamination (i.e.; algae; minerals) to the absolute minimum and valve performance at the absolute maximum.
