This valve is used to control the flow rate of each fluid when several fluids are mixed at a specific rate. The valve comprises a vertical tubular yoke (1), a solenoid (3), a valve stem (5) and a conversion device (6). The yoke has a bottom wall and the solenoid mounted on the upper end of the yoke. The solenoid gives a force of attraction, the magnitude of which is in proportion to the value of input current. The solenoid has an operating rod directed downward and movable longitudinally by the attractive force. A valve body (4) is connected to the bottom wall of the yoke. The valve body stem is vertically movable and supported by the valve body and has an upper portion extending upward from the body into the yoke.
