Heavy Duty Valve Spring Washer High Stress Environments Consistent

In industrial fluid control systems, quick-action stop valves play a crucial role in ensuring safe operation. The core component that supports their stable performance is the valve disc spring. SUNZO Valve Disc Spring is specially designed for quick-action stop valves, providing an indispensable safety guarantee for industrial production.

In the open position of the valve, the SUNZO disc spring stack is under hydraulic preload, maintaining the valve in a stable open state to ensure the smooth circulation of fluids. Once a failure occurs and the hydraulic pressure drops, the spring stack is quickly released, driving the valve to close immediately, effectively preventing potential safety hazards caused by fluid leakage.

To ensure precise operation, SUNZO adopts ball-bearing centered stacks for this application, which greatly improves the stability and service life of the spring stack. In addition, the SUNZO valve disc spring stack has a unique self-adjusting function, which can automatically adjust for the set-loss of gaskets, reducing the frequency of maintenance and saving time and cost for enterprises.

With outer diameters ranging from 16mm to 534mm and thicknesses from 0.4mm to 10mm, SUNZO Valve Disc Spring can meet the needs of different types of quick-action stop valves. We also provide customized services for special valve disc springs; please contact our sales engineers for more details.

• 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
