Systems and methods for sealing micro-valves for use in jetting assemblies

A jetting assembly comprising:

• a valve body comprising an orifice plate including a plurality of orifices extending therethrough;
• and
• a plurality of micro-valves, wherein each of the plurality of micro-valves correspond to an orifice of the plurality of orifices and comprise:
• an actuating beam disposed in spaced relation to the orifice plate, the actuating beam including a base portion and a cantilevered portion, the base portion separated from the orifice plate by a predetermined distance, the cantilevered portion extending from the base portion towards the orifice such that an overlapping portion thereof overlaps the orifice wherein the actuating beam is movable between a closed position and an open position;
• and
• a sealing structure comprising:
• a valve seat surrounding the orifice,
• a sealing member disposed at the overlapping portion of the cantilevered portion, and
• a first sealing blade extending form the sealing member towards the valve seat, wherein the first sealing blade is substantially annular in shape and, wherein the first sealing blade comprises a tip, on a distal end from the sealing member, which provides a focal point for a downward force supplied by the actuating beam to the valve seat when closed.
