This is a pressure relief valve that is installed downstream of a pressure reducing valve and is located in the distribution piping in a fire protection system. If the pressure in the distribution piping rises above the relief valve’s set point, the OCV 1330FC opens and relieves the excess pressure, thus preventing damage.
