Abstract
A fluid control device includes 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 along a first axis and biased toward a closed position in which the control element engages the seat. The fluid control device includes an actuator assembly including a shaft that is operatively coupled to the stem via a Scotch yoke mechanism such that rotation of the shaft in a first rotational direction causes movement of the stem and control element along the first axis in a first translational direction. The actuator assembly includes a trigger mechanism that is responsive to fluid pressure and prevents rotation of the shaft in a first mode of operation and releases the shaft to allow rotation in a second mode of operation.
