ABSTRACT:
A safety valve for use with a beverage dispensing system having a pressurized source connected through a conduit to a container of beverage. The safety valve includes a housing having an inlet for connecting said valve to the pressure source and an outlet for connecting the valve to the beverage container through the conduit. A chamber in the housing is divided into at least two subchambers by a rupture disc which ruptures at a predetermined pressure in one of the subchambers. The other side of the disc is exposed to a subchamber which is vented to the atmosphere. Where the pressure in the one subchamber reaches the predetermined level, the rupture disc will burst allowing the pressurized gas to flow out through a vented chamber into the atmosphere, thereby preventing the container from being over-pressurized.
