A shutter comprising an actuator ring that rotates about a midpoint and three obturator elements movably coupled to the actuator ring. A housing defines a cavity for holding the actuator ring and the obturator elements. The system also includes a plurality of wipers. Each wiper comprises a seal material and acts as a seal disposed between a first or second surface of the obturator elements and a first or second planar surface of the housing. The system also includes curved grooves adapted for receiving a wall seal when valve moves between an open and closed position. When the valve moves between an open and closed position, one end of the obturator element contacts the wall seal and the plurality of wall seals prevent egress of fluid into at least a portion of the cavity of the housing.
