Abstract
A flow control device includes a valve body defining an inlet, an outlet, and a flow path. A valve seat assembly includes a fitting coupled to the valve body, a seat ring coupled to the fitting and defining a valve seat. The seat ring includes an inner groove formed on an interior surface of the seat ring. A control element is movable relative to the valve body between a closed position, in which the control element engages the valve seat, and an open position, in which the control element is spaced away from the valve seat. The seat ring is coupled to the fitting by snap-fit connection such that a portion of the fitting is disposed in the inner groove of the seat ring.
