Venturi devices are disclosed herein that include a body defining a Venturi gap between an outlet end of a converging motive section and an inlet end of a diverging discharge section, having a suction port in fluid communication with the Venturi gap, a gate valve linearly translatable to open and close the Venturi gap, and an actuator connected to the gate valve to operatively move the gate valve between an open position and a closed position. The gate valve, in a longitudinal cross-section, is generally U-shaped, thereby having continuous, opposing sides that one each close the motive outlet and the discharge inlet and defining a void between the opposing sides that is in fluid communication with the suction port. The converging motive section defines a circular-shaped motive inlet and defines an elliptical- or polygonal-shaped motive outlet, and the diverging discharge section defines an elliptical- or polygonal-shaped discharge inlet.
