Pressure regulators are also useful for reducing higher pressures near the pivot point where the sprinkler nozzles are the smallest, thus minimizing plugging, wind drift and evaporation. They are required for use with many of the sprinkler options that have been engineered for operating pressures within a specific range, for optimum water application, extended life of the product and ultimately increased yield.
Pressure regulators eliminate the pressure variation at the sprinkler nozzle caused by:
- Variations in available water supply
- Elevation changes within the field
- Fluctuations in demand such as end guns and swing arm corners
Senninger pressure regulators maintain a constant pre-set outlet pressure that can be matched to the applicator design, regardless of variations in inlet pressure. This helps maintain sprinkler pattern integrity and performance.
