Abstract: A control assembly for a fluid flow control device includes a control element, a load spring, and a spring clip. The control element can be movably disposed for controlling fluid flow, and the load spring biases the control element into a predetermined position. The spring clip contacts the load spring at a plurality of points to dampen vibrations experienced by the load spring, thereby reducing and./or eliminating resonance. The spring clip includes a body plate and first and second opposing arm plates extending away from the body plate. Each arm plate includes a proximal end adjacent the body plate, a distal end spaced away from the body plate, and a finger extending upwardly away from the distal end. A corner at an intersection between the finger and the distal end includes a contoured edge for facilitating attachment of the load spring to the spring clip.
