Pressure relief valves are primarily designed to protect equipment, process, property, the environment, and life.
Allowing processing facilities to operate safely, pressure relief valves often act as the last line of defence against
system overpressure which can cause catastrophic damage.
Pressure relief valves operate by opening at a predetermined set pressure, relieving pressure by releasing process media
until system pressure drops to normal operating level. At this point, the valve closes, successfully preventing damage to
the equipment they are designed to protect.
