Abstract:

The present invention relates generally to valves and more, particularly to a valve for cutting off flow when the pressure differential there across exceeds a predetermined threshold. 2 Description of the Prior Art. Traditional high or low-pressure cut-off valves require mechanical or electrical actuation. However the complexity and or cost associated with such cut-off valves can make them impractical from many applications. Further a particular application may not have the space needed for the installation of the valves associated actuation mechanism Finally, since many cut-off valves close and re-open at the same pressure threshold the valve will tend to chatter if the pressure differential there across rapidly fluctuates about the close re-open pressure threshold.
