The Pre-Set Pressure Regulator is ideal for balancing pressures throughout any medium-flow irrigation system. It is also used for controlling the output of sprays and sprinklers on center pivot and lateral move irrigation systems. At high flow rates, water flows through the Pre-Set Pressure Regulator as smooth as glass; there is minimal turbulence through the regulator. The Pre-Set Pressure Regulator does not chatter. The Pre-Set Pressure Regulator is the perfect tool for pressure control on medium-flow agricultural, nursery, greenhouse, commercial landscaping and homeowner irrigation systems.
