Now standard in Nelson Universal Flo and Hi Flo Pressure Regulators. precision accuracy in tough field environments Nelson’s universal flo and hi flo regulators The function of a pressure regulator is to fix a varying inlet pressure to a set outlet pressure, regardless of changes in the system pressure due to hydraulic conditions, elevation changes, pumping scenarios, etc. The benefits include a uniform depth of water application, controlled sprinkler performance (droplet size and throw distance), and flexibility in system operation. features & benefits: Chemically Resistant Materials Patented Internal Dampening System Retards Vibration & With-stands Water Hammer TECHNICAL TIPS for regulating systems IMPORTANT: Allow approximately 5 PSI (.35 BAR) extra pressure in order for the regulator to function properly. For example, the minimum design pressure for a 20 PSI (1.4 BAR) pressure regulator is 25 PSI (1.7 BAR). IMPORTANT: If your system is designed with Nelson sprinklers, use Nelson Pressure Regulators. Individual manufacturers’ pressure regulator performance varies. Interchanging could result in inaccurate nozzle selection. SINGLE STRUT SEAT Design standard with universal flo. The new “single-strut” technology in the Universal Flo regulator minimizes “hair-pinning”of debris around the inlet seat, providing more plug resistance for systems operating in dirty water condtions. Patented Dampening System. The patented o-ring dampening system of all Nelson pressure regulators handles severe pressure surges to withstand water hammer. wide Flow Range. The Nelson Universal Pressure Regulator has a flow up to 12 GPM (2.7 M3/H) at 15 PSI (1.0 BAR) and above. Extended performance and precision Accuracy. Precision components coupled with an internally lubricated o-ring minimize frictional drag and hysteresis. Precision Manufactured. Made of the toughest chemically resistant materials. 100% tested for accuracy. save water, save energy and do a better job of irrigating universal 3000 series connection option. Integral adapter connects directly into all Nelson 3000 Series Pivot Sprinklers and creates an easy to assemble, economical pivot sprinkler
