This flow control valve works with a very accurate pilot valve, suitable for control of both flow and pressure, to keep a preset flow value, to limit any excess of flow or upstream pressure, while downstream will not change, even if the pressure of main valve may change in downstream. Very high accuracy of level control, debug service, easy to install and to maintain.
