Enables a backup supply of oxygen to automatically deliver gas if the HVO tank pressure drops below its normal regulator pressure. This might happen if, for example, you have a power failure, or a spike in oxygen demand.

The product is essentially a “T” that sits between a backup oxygen source, such as a compressed oxygen tank, and the HVO system. Each side requires a regulator, i.e. one for the HVO system and one for the backup supply, as shown in the diagram at left.
On the backup supply side there’s a ball valve (at right above) that enables the backup source to be turned off. On the HVO side there’s a check valve (at left above), a safety mechanism which ensures that the HVO tank won’t receive oxygen from a high-pressure supply. In the middle, there’s a “T” that connects to your oxygen-out line.
