A Compression Spring is designed and constructed to resist the compressive load applied to it. When a compressive force is applied, the coils are compressed and the spring stores the energy. The shape of the Compression Spring is cylindrical, with a helical coil that is tightly wound to resist compression.Attributes:• Direction of coils is Right Hand with Total Coils 20.75 and Active Coils 18.75• Helps to prevent reverse flow, minimizes water hammerApplications:A Compression Spring is used in a sequence and pressure control valve to control and regulate the fluid flow within the valve.
