ABSTRACT:
A stem regulator for direct mounting on the valve of a high pressure gas cylinder to provide a reduced delivery pressure for components or circuits of lesser pressure rating. The main body of the regulator, which contains its working parts, is adapted to serve, for example, as an inlet nipple for connecting the cylinder valve to a conventional adjustable pressure regulator. At one end, the body has a cylinder valve coupling face and nut and at the appropriate end has an adaptor threaded to mate with the conventional regulator. A compact design and straight-through flow path of the regulator simplifies installation and ensures durability.
