Abstract
A valve for controlling delivery of fluid includes a valve seat comprising a fluid inlet, a fluid outlet and a conical well having an opening, a beveled surface and a bottom, and a valve membrane comprising a conical portion having a base and a tip. The conical portion is configured to fit within the conical well of the valve seat. The valve membrane is configured to fluidly connect the fluid inlet to the fluid outlet when the valve membrane is in an undeformed position and fluidly disconnect the fluid inlet from the fluid outlet when the valve membrane is in a radially deformed position.
