Pressure relief valve having a bursting disk for a beverage dispenser

摘要

A valve assembly for filling a bag with a beverage under pressure has a valve body having a first passageway extending therethrough and a first valve seated in the first passageway for controlling the flow of beverage through the first passageway into and out of the bag. A pressure relief passageway extends through the valve body from inside the bag to within the container. A bursting disk is seated with the valve body normally closing the pressure relief passageway and is adapted to rupture permitting fluid to escape from the bag through the pressure relief passageway and into the container surrounding the bag when the pressure in the bag exceeds a predetermined pressure value.
