7.4 - CHECK THAT THE RELIEF VALVE IS WORKING PROPERLY
• Start the system and set the shut off as described in point 4.0;
• Slowly close the valve downstream of the regulator;
• Loosen and remove the cap (
26
);
• Use an 8 mm socket spanner to press the adjustment nut (
4
) to increase the pressure Pa above the preset value, while
preventing the OPSO shut off from being triggered. Use a calibrated pressure gauge for the reading;
• Remove the socket spanner. The generated overpressure will be discharged outwards and the Pa will begin to decrease to
the relief valve setting value. Relief valve operation is verified;
• Close the cap (
26
);
• Open the relief valve to discharge the created overpressure;
• Close the relief valve (the regulator goes to the closing pressure) and open the ball valve downstream of the regulator.
