Product Description
Industrial Valve Actuators & Severe Process Piping
High-Performance Disc Spring Stack for Industrial Valve Actuators
In the demanding environments of fluid control and chemical processing, maintaining precise, continuous torque and linear force is essential for operational safety. Jiangsu Sanzhong Elastic Technology Co., Ltd. offers precision-engineered Disc Spring Stack configurations specifically optimized for heavy-duty industrial valve actuators and emergency shutdown (ESD) systems. When conventional coil springs fail due to space constraints or high force requirements, our custom-stacked disc springs provide a reliable solution, ensuring consistent valve seating and preventing catastrophic fluid leakage.
SERIES-PARALLEL (COMBINED) STACK TYPE
This configuration provides BOTH increased load capacity AND increased deflection capability.

Key Benefit: Ideal for large-diameter control valves requiring high initial seating force combined with long sealing strokes.
Our engineering team analyzes the specific force-deflection curves required for automated valve systems. By configuring the Disc Spring Stack in various orientations—such as series, parallel, or progressive combinations—we customize the spring rate to match the exact mechanics of pneumatic, hydraulic, or electric actuators. This precision minimizes friction loss, reduces hysteresis, and extends the operational lifespan of the entire valve assembly, even under constant cycling.
Target Client Applications
- Pneumatic & Hydraulic Valve Actuators: Integrated into spring-return actuators for quarter-turn ball valves and linear gate valves to ensure reliable emergency closing.
- Petrochemical Control Valves: Installed within packing glands and main control valve stems to compensate for packing wear and thermal relaxation.
- Refinery Piping Infrastructure: Positioned on high-pressure flange bolting systems to absorb sudden thermal expansion and prevent fugitive emissions.
