A motorized fluid control valve includes a valve unit having a fluid inlet and outlet provided in a tube for controlling fluid flow, wherein the valve unit is adapted to operate between an opened and closed position. The motorized fluid control valve includes a motor and a driving pin providing a rotational power, a cam including a cam body rotatably mounted in such a manner that the motor is arrange to drive the cam body to rotate to operate the valve unit and to produce a valve signal showing a corresponding position of the valve unit. The motorized fluid control valve includes a valve safety arrangement having two fingers. When the valve unit is stuck, the driving pin will break the two fingers to disengage the cam from the motor, thus stopping any further rotation of the cam and provide a true signal regarding the position of the valve unit.
