    Abstract: A flow control valve for a flow controller includes a valve main body provided with an open-top valve chamber hole, a metal diaphragm valve element, a lower support cylinder having notches facing each other, an upper support cylinder attached to the lower support cylinder, a support frame horizontally disposed through the notches of the lower support cylinder, a disc spring placed between the support frame and a bottom of the lower support cylinder, a lower cradle placed on the support frame, a piezoelectric element inserted into the support cylinder above the lower cradle, a guide fixed to the valve main body together with the support frame with the support cylinder being inserted through the guide cylinder in a vertically movable manner. The support cylinder is pressed upward by the extension of the piezoelectric element, whereby the metal diaphragm valve element is separated from the valve seat by the elastic force.
