A Compression Spring is used in a Relief Valve that helps to regulate the pressure of a fluid. The spring is typically used to control the movement of a valve or other part that regulates the pressure of the fluid. The shape of the Compression Spring is cylindrical, with a helical coil that is tightly wound to resist compression.Attributes:• Coils of the spring wrap around the axis of the spring in a clockwise direction when viewed from the top• Provides a constant force over a wide range of deflectionsApplications:A Compression Spring provides support and maintains proper alignment between parts.
