800 Series Pressure Reducing Valves

Accurately maintain a constant downstream pressure regardless of changing flow rate or upstream pressure.


Pressure reducing valves are used anywhere you need to reduce a higher inlet pressure to a lower outlet pressure. Applications include center pivot points, sprinkler and drip irrigation zone control valves, gravity-fed mainlines, and submain turnouts. The Nelson pressure control pilot is famous for precision accuracy and responsiveness, to ensure stable pressure regulation.

  • Accurate 3-way control pilot reduces filtration requirements
  • Adjustment ranges for 2" and 3" valves: 5-30 psi / 5-60 psi / 10-120 psi
  • Adjustment ranges for 4-8" valves: 5-50 psi / 10-120 psi / 25-200 psi
  • Can be combined with other functions, including solenoid on/off, pressure sustaining, and rate-of-flow.
