ABSTRACT:
A pressure activated valve incorporates arrangements of permanent magnets within the valve housing to establish a pressure threshold at which the valve is either opened or closed. The magnets are mounted relative to one another with opposing polarities; so that the repelling force between the magnets establishes the pressure threshold at which the valve is operated.
