ABSTRACT:
A valve which controls either the injection of fluid from an exterior source into the interior of the valve housing or the exhausting of fluid pressure from the valve housing. The valve is especially adapted for controlling the injection of fluid into a wireline lubricator assembly. Alternative means are provided for opening and closing the valve. Preferably a metal-to-metal seal is used to control fluid flow.
