A shutter valve for regulating pressure and controlling fluid flow comprising an actuator ring having a plurality of gear teeth, the gear teeth driven by a mating gear or other means. A plurality of obturator pin bosses, each pin boss affixed within an inside circumference of the actuator ring, the pin boss further comprising a hinge pin aperture. The shutter valve further comprises three or more obturator elements, each obturator element defining a petal shape structure including a tongue and groove feature along at least a portion of an outside circumference thereof, and wherein each obturator element is hingedly coupled to a hinge pin aperture of an obturator pin boss. A hook element is located at an apex of said petal shape structure of each obturator element. The shutter value further includes a housing defining a cavity or holding the actuator ring and the three or more obturator elements.

The shutter valve of claim 1, wherein the petal shape structure of each obturator element further comprises a seal surface along at least the portion of the outside circumference thereof. 3. The shutter valve of claim 2, wherein said seal surface is composed of any one of rubber, plastic, PTFE, and vinyl. 4. The shutter valve of claim 3, wherein said actuator ring comprises a flat surface to mate with a seal. 5. The shutter valve of claim 4, wherein each of said three or more obturator elements is coupled by a hinge to the hinge aperture of the obturator pin boss such that said three or more obturator elements are arranged in a circular array along the inside circumference of the actuator ring. 6. The shutter valve of claim 5, wherein said three or more obturator elements are communally disposable between an open position and a closed position. 7. The shutter valve of claim 6, wherein in the closed position the seal surface of each obturator element contacts an adjacent obturator element so as to occlude any aperture within the inside circumference of the actuator ring. 8. The shutter valve of claim 7, wherein forces acting on the gear teeth drive the actuator ring, causing the obturator elements to move between the open and closed positions. 9. A shutter valve for regulating pressure and controlling fluid flow, comprising: an actuator ring comprising: a) a plurality of gear teeth, the gear teeth driven by a mating gear;b) a plurality of obturator pin bosses, each obturator pin of the plurality of obturator pin bosses boss affixed within an inside circumference of the actuator ring;and c) a hinge pin aperture located in each obturator pin boss;three or more obturator elements, each obturator element of the three or more obturator elements comprising: a) a petal shape structure including a tongue and groove feature along at least a portion of an outside circumference thereof, wherein the tongue and groove feature includes a ridge on a first side of the portion of the outside circumference and a channel on a second side of the portion of the outside circumference;b) a hook element located at an apex of said petal shape structure; andc) a hinged connection to the hinge pin aperture of the obturator pin boss, such that rotational movement of the actuator ring causes movement of an obturator element; anda housing defining a cavity for holding the actuator ring and the three or more obturator elements. 10. The shutter valve of claim 9, wherein the petal shape structure of each obturator element further comprises a seal surface along at least the portion of the outside circumference thereof. 11. The shutter valve of claim 10, wherein said seal surface is composed of any one of rubber, plastic, PTFE, and vinyl. 12. The shutter valve of claim 11, wherein said actuator ring comprises a flat surface to mate with a seal. 13. The shutter valve of claim 12, wherein said three or more obturator elements are arranged in a circular array along the inside circumference of the actuator ring. 14. The shutter valve of claim 13, wherein said three or more obturator elements are communally disposable between an open position and a closed position. 15. The shutter valve of claim 14, wherein in the closed position the seal surface of each obturator element contacts an adjacent obturator element so as to occlude any aperture within the inside circumference of the actuator ring. 16. A shutter valve for regulating pressure and controlling fluid flow, comprising: an actuator ring comprising: a) a plurality of gear teeth, the gear teeth driven by a mating gear;b) a plurality of obturator pin bosses, each obturator pin boss of the plurality of obturator pin bosses affixed within an inside circumference of the actuator ring;and c) a hinge pin aperture located in each obturator pin boss;three or more obturator elements, each obturator element of the three or more obturator elements comprising: a) a petal shape structure including a tongue and groove feature along at least a portion of an outside circumference thereof, wherein the tongue and groove feature includes a ridge on a first side of the portion of the outside circumference and a channel on a second side of the portion of the outside circumference;b) a hook element located at an apex of said petal shape structure;c) a hinged connection to the hinge pin aperture of the obturator pin boss, such that rotational movement of the actuator ring causes movement of the obturator elements; andd) a protrusion configured for gliding along a track; anda housing defining a cavity for holding the actuator ring and the three or more obturator elements, the housing comprising a plurality of tracks, each track configured for receiving a protrusion of an obturator element, such that the protrusion glides along the track. 17.
