Features & Key Benefits
PRV9i offers a number of features and key benefits:
The outlet pressure can be preset to give a constant outlet pressure of 3.5 bar up to 9 bar, with flow rates in excess of 1200 l/m. This controlled outlet pressure can be easily modified on site under flowing conditions to accommodate varying inlet pressures due to pump variations and pipe work variations. A calibration certificate will be issued to guarantee operation under the required pressure.
The outlet pressure of the unit is controlled by adjusting the spring compression. This can be done easily in situ during flowing conditions using the minimum of basic tools such as a spanner, allen key and tubular spanner. The adjustment unit is enclosed and locked to help prevent unauthorised personnel from interfering with this function.
