    Notes

    • It is recommended to install an exhaust valve on the top of the riser to make the pressure reducing valve work more smoothly.
    • Before installing the pressure relief valve, check the valve for unusual items and be sure to flush the pipeline.
    • Installation method: Horizontal or vertical installation, single valve set.

    Tips: What are the advantages of a pilot-operated pressure relief valve?

    Like other pressure relief valves (PRV), pilot-operated relief valves (PORV) are used for emergency relief during overpressure events (e.g., a tank gets too hot and the expanding fluid increases the pressure to dangerous levels).

    • The smaller package on the larger pipe sizes.
    • More options for control.
    • Seals more tightly as the system pressure approaches but does not reach set pressure.
    • The control pilot can be mounted remotely.
    • Some designs allow for changes in orifice size within the main valve.
    • The PORV can be used in engines.
    • Higher Operating-to-Set Pressure ratio.
