a flexible member having a movable free end and being disposed between the first channel and the second channel, the movable free end of the flexible member being disposed for movement onto and off of the valve seating portion by means of an actuating force such that movement of the movable free end onto the valve seating portion prevents fluid flow between the first channel and the second channel and movement of the movable free end off of the valve seating portion allows fluid flow between the first channel and the second channel.

[ What is claimed is:] [1.] A method for controlling fluid flow by means of a plate-type valve, said plate-type valve comprising:a first valve plate having a first channel formed therein, said first valve plate being formed of a first charged material;a second valve plate having a second channel formed therein and a valve seating portion, said second valve plate being formed of a second charged material; anda flexible member having a movable free end and being disposed between the first channel and the second channel, said flexible member being cantilevered at one end thereof to said first valve plate;wherein the first and second plates are capable of being charred to polarities so as to provide between said flexible member and said valve seating portion (i) an electrostatic attraction force so as to cause the movable free end of the flexible member to move onto the valve seating portion, and (ii) an electrostatic repulsion force so as to cause the movable free end to move away from the valve seating portion; wherein movement of the movable free end onto the valve seating portion prevents fluid flow between the first channel and the second channel and movement of the movable free end away from the valve seating portion allows fluid flow between the first channel and the second channel;wherein said method comprises (i) charging said first and second plates to opposite polarities to provide an electrostatic attraction force between the flexible member and the valve seating portion so as to cause the movable free end of the flexible member to move onto the valve seating portion so as to prevent fluid flow between the first channel and the second channel; and/or (ii) charging said first and second plates to like polarities to provide an electrostatic repulsion force between the flexible member and the valve seating portion so as to cause the movable free end of the flexible member to move away from the valve seating portion so as to allow fluid flow between the first channel and the second channel.
