Features and Benefits
. Maintains a set outlet pressure regardless of inlet pressure changes due to hydraulic conditions, elevation changes, pumping scenarios, etc.
. Wide Flow Range to 12 gpm at 15 psi and above.
. Plug-Resistant Design -- an open seat design prevents hair-pinning, debris hang-up, and plugging.
. Patented Dampening System -- handles severe pressure surges to withstand water hammer.
. Chemically Resistant Materials.
. Extended Performance & Precision Accuracy -- Precision components coupled with an internally lubricated o-ring minimize frictional drag and hysteresis.
. Integral adapter connects directly into all Nelson 3000 Series Sprinklers.
