Piloted regulators Before reading it would be better to understand about **[Pressure regulators](http://instrumentpedia.blogspot.com/2015/06/basics-of-pressure-regulator-pressure.html)** Set point determined by pilot (a direct acting regulator) that control the flow to or from the diaphragm of a larger valve May have minimum differential pressure requirement . Larger line sizes for higher flows Very accurate Higher turndown ratios Requires minimum differential pressure and downstream sensing tap Advantages of Piloted Regulators More accurate Less drop More sensitive - Small change in pilot = large change in main valve Higher range ability Disadvantages of piloted regulators More sensitive - Can create oscillations with in a system Not good for rapidly changing system Requires minimum pressure drop to operate (typically 15-25 psi)
