An Auxiliary Control Valve Spring generates a restoring force that acts between the plug and the stem to influence valve movement. When an external force displaces the stem, the spring compresses and extends, storing mechanical energy that is released when the applied force decreases. This action supports controlled return of the stem toward its initial position, enabling regulated interaction between the plug and flow passages. By opposing the applied force, the spring helps maintain balanced motion and prevents abrupt changes in position.Attributes:• Generates restoring force between the plug and stem during displacement and return motion.• Supports controlled movement of the stem by opposing the applied actuation force.• Stores mechanical energy during compression or extension for release during return.Applications: An Auxiliary Control Valve Spring is used to provide restoring force between the plug and stem to control movement and return positioning during valve operation.
