Abstract
A flow rate control valve comprises a rotary driving source which is rotated by a control signal, a movable member which is displaceable by the aid of a transmitting shaft under a rotary action of the rotary driving source, a valve mechanism which is connected to the end of the movable member and which is capable of being seated on and separated from a valve seat of a valve body, and a balance mechanism which is integrally connected underneath the valve mechanism with a connecting shaft intervening therebetween. When the valve opening degree is changed in a state in which pressure fluid is supplied into the valve body, the balance mechanism maintains an equilibrium state with respect to the valve mechanism.
