Abstract: A gas regulator includes a valve chamber body that houses two valves of the regulator. Valve elements that move to open and close the two valves are received via a same opening into the valve chamber body, which is closed by a plug. The plug can define a first valve seat as well as a piercing element used to pierce a compressed gas cylinder. A retainer can hold a gasket at a valve seat as well as provide a bore or other support for a valve element and valve element spring.

Abstract: A system and method for transferring beverage such as wine from a source container to a destination container. First and second transfer heads can be configured to sealingly engage with an opening of source and destination containers, respectively. The container opening(s) can have a closure such as a cork or septum and the transfer heads can sealingly engage with the container opening without removing the closure, e.g., by passing one or more needles through the closure. The transfer heads and the source container can be held by a support, and the first transfer head can be mounted for pivotal movement relative to the support, e.g., about a horizontal axis, to accommodate differently sized and/or shaped containers. Pressurized gas, e.g., used to purge and/or pressurize the containers, and beverage flow can be routed from one of the transfer heads to the other.
