Claim 16:
17. A method for manufacturing a microvalve assembly, the method comprising:
providing a body comprising first and second ports and a body plate;
coupling a stack to one or more exterior plates to form an actuator assembly disposed within the body and between the first and second ports;
coupling at least one spring to the body and the actuator assembly such that the spring is configured to apply a force to the actuator assembly to cause one of the one or more exterior plates to contact the body plate to form a seat and thereby restrict fluid flow from the first port to the second port; and
electrically connecting the stack to an energizing system configured to energize the stack to periodically generate a gap between the one of the one or more exterior plates and the body plate via near-field-acoustic-levitation (NFAL) to allow fluid flow through the first and second ports.
