8. Disc spring stacks are under hydraulic preload in the open position in quick-action valves. After a failure, the hydraulic pressure drops and releases the spring stack, hence closing the valve. This application mainly uses ball bearing centered stacks. In addition, the spring stack has a self-adjusting function by countering the set-loss of gaskets. This conserves overhead costs as it minimizes required maintenance
