RUPTURE DISC SAFETY VALVE ABSTRACT OF THE DISCLOSURE 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 prede- termined 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.
