Abstract:
A control device includes a valve body, a seat ring, and an actuator. The valve body defines a flow-path for a fluid. The seat ring is disposed within the flow-path. The actuator is coupled to the valve body and includes a control member. The control member is adapted for displacement relative to the seat ring for regulating a flow of the fluid through the flow-path. The control member includes a scaling disk adapted to sealingly engage the seat ring and close the flow-path. The seat ring includes an orifice disposed within the flow-path such that the seat ring prevents at least a portion of the flow of the fluid from substantially perpendicularly impacting the sealing disk.
