A Compression Spring used in a Push-Pull Control Valve is used to provide a specific amount of force to the valve spool. The valve spool is a cylindrical part that is responsible for directing the flow of fluid through the valve. The shape of the Compression Spring is cylindrical, with a helical coil that is tightly wound to resist compression in the valve.Attributes:• The direction of the coil is Right Hand• Provided with a spring rate of 127 N/mm, which provides high stiffness to the spring• Provides a constant force over a wide range of deflectionsApplications:A Compression Spring is used to provide the necessary restoring force to ensure proper valve operation.
