A control assembly for a fluid flow control device (10) includes a control element (16), a load spring (44), and a spring clip (42). The control element (16) can be movably disposed for controlling fluid flow, and the load spring (44) biases the control element (16) into a predetermined position. The spring clip (42) contacts the load spring (44) at a plurality of points to dampen vibrations experienced by the load spring, thereby reducing and/or eliminating resonance. The spring clip (42) includes a body plate (58) and first and second opposing arm plates (60a, 60b) extending away from the body plate. Each arm plate includes a proximal end (68a, 68b) adjacent the body plate, a distal end (70a, 70b) spaced away from the body plate, and a finger (72a, 72b) extending upwardly away from the distal end. A corner (74a, 74b) at an intersection between the finger and the distal end includes a contoured edge (76a, 76b) for facilitating attachment of the load spring to the spring clip. The spring clip can better dampen vibrations and reduce and/or eliminate resonance. |
