Product Description
Detailed Specifications & Features
Thermal-Resistant Multi Turn Wave Spring for High-Temperature Control Valves
Industrial control valves operating in chemical plants and steam generation systems are subject to continuous thermal cycling and high pressures. Jiangsu Sanzhong Elastic Technology Co., Ltd. offers a premium line of Multi Turn Wave Spring products designed to maintain constant sealing pressure under these demanding conditions. These crest-to-crest flat wire springs fit directly into valve packing boxes and actuator mechanisms, compensating for material relaxation and preventing fugitive emissions.

Constant Sealing Force Retained
Standard carbon steel springs lose their elasticity quickly when exposed to high operating temperatures. Our facility utilizes advanced nickel-chromium superalloys to manufacture wave springs that resist stress relaxation at high temperatures. By maintaining constant tension on graphite or PTFE packing materials, our multi-turn wave springs prevent fluid leakage along the valve stem, helping processing facilities meet strict environmental regulations.
Target Client Applications
- Refinery Control Valves: Installed in high-temperature steam, hydrocarbon, and chemical processing valves to maintain stem packing load.
- Pressure Relief Valves (PRV): Used as compact internal calibration springs to ensure repeatable opening and closing pressures.
- Pneumatic Diaphragm Actuators: Integrated as return springs within compact actuator housings to ensure reliable valve positioning.
Technical Specifications & Product Parameters
- Superalloy Options: Inconel X-750 (UNS N07750), Inconel 718, and Nimonic alloys tailored for extreme environments.
- Max Temperature Threshold: Capable of continuous operation at temperatures up to +650°C without significant load loss.
- Dimensional Conformance: Engineered according to precise customer design specifications and international spring tolerances.
- Free Height (L₀) Scope: Fully customizable depending on the required turn count, extending from 2.0 mm up to 150.0 mm.
- Corrosion Resistance: High resistance to intergranular oxidation, sour gas (H₂S), and chloride-induced cracking.
