Abstract

A fluid control device comprising including a body having an inlet, an outlet, and a fluid flow path between the inlet and the outlet, a seat, and a control element that is coupled to a stem. The control element and the stem are movable relative to a longitudinal axis and biased toward a closed position, in which the control element engages the seat. An actuator assembly is operatively coupled to the stem and includes a planetary gear transmission mechanism configured to receive a first rotational velocity and to deliver a second rotational velocity different than the first rotational velocity. A shaft has a first end coupled to the transmission mechanism and a second end coupled to valve stem. The second rotational velocity is transmitted to the valve stem to move the control element between the closed position and an open position.
