The primary purpose of a pressure relief device is to protect a single vessel from overpressure. They do not protect against structural failure when the ship is exposed to extremely high temperatures, such as during a fire.
A pressure relief valve is a pressure relief device designed to open and relieve excess pressure and close again to prevent further fluid flow after normal conditions are restored. A pressure relief valve opens when the upstream pressure reaches the set pressure. It then allows the fluid to flow until the upstream pressure drops to the shut-off pressure (the shut-off pressure value is lower than the set pressure and will be reached after the blowing phase is completed). It then closes and prevents further flow.
Types of pressure relief valves include relief valve, relief valve, normal relief valve, balanced safety relief valve and pilot operated pressure relief valve.
