1. A shutter valve for regulating pressure and controlling fluid flow, comprising: an actuator ring, the actuator ring further comprising a plurality of gear teeth, the gear teeth driven by a mating gear;a plurality of arm pin bosses, each pin boss affixed within an inside circumference of the actuator ring, the arm pin boss further comprising a hinge pin aperture;three or more pivot arms, each pivot arm having a first end and a second end, the first end mounted to a hinge pin aperture of an arm pin boss;three or more obturator elements, each obturator element comprising: a) a petal shape structure including a tongue and groove feature along at least a portion of an outside circumference thereof;b) a hook element located at an apex of said petal shape structure of each obturator element; andc) a hinged connection to a second end of a pivot arm; anda housing defining a cavity for holding the actuator ring, the pivot arms and the obturator elements. 2. The shutter valve of claim 1, wherein the petal shape structure of each obturator element further comprises a seal surface along at least a portion of the outside circumference thereof. 3. The shutter valve of claim 2, wherein said seal surface of said tongue and groove feature is composed of any suitable seal material. 4. The shutter valve of claim 3, wherein said actuator ring comprises a flat sealing surface with a flat texture. 5. The shutter valve of claim 4, wherein the 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 securely void 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, the actuator ring further comprising a plurality of gear teeth, the gear teeth driven by a mating gear;a plurality of arm pin bosses, each pin boss affixed within an inside circumference of the actuator ring, the arm pin boss further comprising a hinge pin aperture;three or more pivot arms, each pivot arm having a first end and a second end, the first end hingably mounted to a hinge pin aperture of an arm pin boss, such that rotational movement of the actuator ring causes movement of the pivot arms;three or more obturator elements, each obturator element comprising: a) a petal shape structure including a locking feature along at least a portion of an outside circumference thereof;b) a hook element located at an apex of said petal shape structure of each obturator element;c) a hinged connection to a second end of a pivot arm, such that movement of the pivot arm causes movement of the corresponding obturator element; andd) a hinged connection to a housing; anda housing defining a cavity for holding the actuator ring, the pivot arms and the obturator elements, further comprising a plurality of hinge pin apertures for coupling to hinged connections to 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 a portion of the outside circumference thereof. 11. The shutter valve of claim 10, wherein said seal surface of said locking feature is composed of any suitable seal material. 12. The shutter valve of claim 11, wherein said actuator ring comprises a flat sealing surface with a flat texture. 13. The shutter valve of claim 12, wherein the 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 securely void any aperture within the inside circumference of the actuator ring. 16. The shutter valve of claim 15, wherein forces acting on the gear teeth drive the actuator ring, causing the obturator elements to move between the open and closed positions. 17. A shutter valve for regulating pressure and controlling fluid flow, comprising: an actuator ring, the actuator ring further comprising a plurality of gear teeth, the gear teeth driven by a mating gear;a plurality of arm pin bosses, each pin boss affixed within an inside circumference of the actuator ring, the arm pin boss further comprising a hinge pin aperture;three or more pivot arms, each pivot arm having a first end and a second end, the first end hingably mounted to a hinge pin aperture of an arm pin boss, such that rotational movement of the actuator ring causes movement of the pivot arms;three or more obturator elements, each obturator element comprising: a) a petal shape structure including a locking feature along at least a portion of an outside circumference thereof;b) a hook element located at an apex of said petal shape structure of each obturator element;c) a hinged connection to a second end of a pivot arm, such that movement of the pivot arm causes movement of the corresponding obturator element; andd) a hinged connection to a housing; anda housing defining a cavity for holding the actuator ring, the pivot arms and the obturator elements, comprising: a) a plurality of hinge pin apertures for coupling to hinged connections to obturator elements; andb) a plurality of walled protrusions within said cavity, each walled protrusion providing a surface against which a primary surface of each obturator element slides when the obturator elements move. 18. The shutter valve of claim 17, wherein the petal shape structure of each obturator element further comprises a seal surface along at least a portion of the outside circumference thereof. 19.
