reducing valve

A device to reduce the pressure of gas that has been compressed in a cylinder.

1. a membranous fold in a canal or passage that prevents backward flow of material passing through it.
2. a mechanical device to regulate the flow of liquid or gas from an area of higher pressure to one of lower pressure.
3. automatic valve which maintains a steady vacuum in the system of a mechanical milking machine.

reducing valve
