The Spool Valve Backup Ring serves as a backup for the primary seals, ensuring that they maintain their integrity and prevent the leakage of hydraulic fluid under high-pressure conditions. It provides a physical barrier that prevents the extrusion of the primary seals, which can occur due to the high pressures and dynamic movements within the spool valve. By supporting the seals, the backup ring helps to maintain a tight and secure seal, ensuring the efficient and reliable operation of the hydraulic control unit.Attributes:• Provides reliable and consistent sealing performance, even under the demanding conditions• Withstand exposure to harsh environmental factors, such as extreme temperatures, vibrations, and exposure to hydraulic fluidsApplications:The Spool Valve Backup Ring prevents the extrusion of the primary seals, which can occur due to the high pressures and dynamic movements within the spool valve.
