Pilot opertaed pressure relief valve is one of main types of pressure relief devices (PRDs), which are used to provide a means of venting excess pressure to protect a boiler or pressure vessel from rupturing. ATO offers 2 inch/3 inch/4 inch/5 inch/6 inch/8 inch/10 inch high-accuracy pilot operated pressure relief valve for selection. 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).
