Pressure Relief Valves (PRV)

Spring actuated pressure relief valves (PRV) are direct acting, relying on a system's hydraulic pressure to open when the spring’s preset force has been exceeded. When the inlet fluid pressure rises and overcomes the spring set pressure, the sealing device is lifted off its seat and discharges fluid to the outlet. When pressure falls below the setting, the sealing device moves back on to its seat and fluid passes downstream.
