ABSTRACT:
The valve has a sphere that is resiliently biased by a resilient lever means to close the outlet orifice leading from the frustoconical seat on which the sphere is seated. Associated with the resilient lever means is an electric-operated actuator that is effective, when energized, to release the resilient bias force which the resilient lever means exerts on the sphere. When this happens, a spring that is disposed to bear against the sphere unseats the sphere thereby opening the valve.
