Abstract
A fluid valve apparatus particularly for pneumatic service (air or other gases) in a filter/separator for opening and closing a valve in response to the level of liquid in a container. The apparatus includes a valve having a magnetically attractable portion and a float having a magnet therein adjacent but physically separated from the valve for opening and closing the valve magnetically in response to changes in the liquid level within the container. In the preferred embodiment, the valve apparatus is used with a filter/separator in an air pressure supply line to automatically dump water and other liquids condensed from the air supply and collected in the filter reservoir.
