High-Temperature Valve Packing & Gland Sealing
Thermal-Resistant Inconel Wave Spring for Industrial Control Valve Packing

In high-temperature fluid processing, industrial control valves often suffer from leakage due to thermal cycling and packing degradation. Standard carbon or stainless steel springs frequently experience stress relaxation under high temperatures, leading to lost sealing pressure and hazardous fugitive emissions. To address this challenge, Jiangsu Sunzo Spring Elastic Technology Co., Ltd. provides precision-engineered Inconel Wave Spring components designed to maintain stable axial tension on valve packing glands over long operational lives.

Our Inconel wave springs utilize flat-wire crest-to-crest geometry, allowing them to deliver equivalent spring forces at half the operating height of conventional helical coil springs. This space-saving profile enables engineers to design shorter valve bonnets, reducing overall weight and material costs while maintaining reliable sealing performance under continuous thermal movement.

Target Client Applications
  • Petrochemical Refinery Valves: Installed in high-temperature hydrocracker, distillation, and thermal cracking valves to prevent stem leaks.
  • Steam Distribution Systems: Integrated into main steam isolation valves (MSIV) and pressure-reducing stations exposed to continuous high-temperature steam.
  • Chemical Processing Plants: Applied to packing glands handling hot, aggressive organic acids and corrosive chemical mediums.
