A Compression Spring is designed to resist compression and absorb shock. It consists of a helical coil formed by tightly wound wire. The load characteristics of a Compression Spring define how it responds to the applied forces. The Spring Rate represents the change in force per unit change in the length of the spring. It is located between the Retainer and Valve Housing in the Relief Valve.Attributes:• Manufactured to precise specifications and are built for durability and reliability• Designed to withstand high and low-temperature environmentsApplications:A Compression Spring is used in Relief Valve to determine the set pressure at which the valve opens.
