    Tips: Does a pressure relief valve reduce flow?

    Yes, the purpose of a pressure relief valve is to control or limit surges of pressure within pipelines, acting as protection for the system, and defending against instrument or equipment failure. But this only occurs when pressure exceeds the set pressure. During normal operation, pressures should not exceed the set level, and the relief valve remains closed.
