Summary: | A subsea pressure relief valve includes a water-filled nozzle fluidly connected to a hydrocarbon distribution manifold. A valve body is connected to the distribution manifold, with an outlet of the nozzle coincident with an interior water-filled chamber of the valve body. A first seal element is removably seated against the nozzle outlet and an arm is hinged to the body and configured to apply a force along a seal axis and bias the first seal element into sealing engagement with the nozzle outlet until hydrocarbon pressure exceeds a sealing pressure of the applied force and unseats the first seal element from the nozzle outlet such that excess hydrocarbons exit through an outlet of the valve body. A weight is disposed on the arm at a distance from the seal axis. |
