3/4" Pressure Regulators

Benefits of pressure regulation include a uniform depth of water application, controlled sprinkler performance (droplet size and throw distance), and flexibility in system operation. 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 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.
The patented o-ring dampening system of all Nelson pressure regulators handles severe pressure surges to withstand water hammer.
The Nelson Universal Pressure Regulator has a flow up to 12 GPM (2.7 M3/H) at 15 PSI (1.0 BAR) and above.
Precision components coupled with an internally lubricated o-ring minimize frictional drag and hysteresis.
Made of the toughest chemically resistant materials. 100% tested for accuracy.

Mini Regulator Drain Check

Ensure high uniformity and even flow throughout your system and eliminate the effects of pressure gains and losses due to uneven topography or high friction loss.The drain check feature eliminates sprinkler drizzle during shut down and start up. Choose from 20, 30, 35, 40, 45, 50 or 60 PSI (1.4, 2.1, 2.4, 2.8, 3.1, 3.4 or 4.1 BAR) nominal pressures.

Eliminate wash out and erosion damage caused by partially pressurized sprinklers during system start up and shut down.
The Acme thread connects directly to Nelson Rotator Sprinklers (R5-R2000WF), the S10, D10, R10TG and to Nelson Feedtube assemblies.
The Nelson Mini Regulator and Drain Check has a flow range from 0.15 to 5 GPM at a maximum inlet pressure of 150 PSI.
Precision components coupled with an internally lubricated o-ring minimize frictional drag and hysteresis.
Made of the toughest chemically resistant materials. 100% tested for accuracy.

Mini Drain Check

The MDC is a check valve only that opens 2-5 PSI (.14-.35 BAR) below the nominal pressure rating. Available in 20 and 35 PSI (1.4-2.4 BAR) options. Ideal when a check feature only is needed or when it is necessary to operate sprinklers at different pressures that best suit environmental conditions. Perfect for overhead cooling of apples and other crops. The MDC prevents draining of the sytem in between frequent on / off cooling cycles.

Nelson Mini Pressure Regulator

Mini Regulator

For systems in which pressure ranges are excessive, the Nelson Mini Regulator provides uniform flow and distribution at each sprinkler through pressure regulation. Ensure high uniformity and even flow throughout your system and eliminate the effects of pressure gains and losses due to uneven topography or high friction loss. Choose from 20, 30, 35, 40, 45, 50 or 60 PSI (1.4, 2.1, 2.4, 2.8, 3.1, 3.4 or 4.1 BAR) nominal pressures.
