High-Temperature Pneumatic Flue Gas Valve

The ‌High-Temperature Flue Gas Butterfly Valve‌ is an industrial valve specifically designed for high-temperature flue gas pipelines (such as those in metallurgy, power generation, and chemical industries). It controls or regulates the flow of high-temperature exhaust gases through a rotating disc. Its key features include:

1. High-Temperature Resistance‌

• Constructed from materials like ‌310S stainless steel‌ or ‌high-temperature alloy 2520 (0Cr25Ni20)‌, capable of enduring temperatures ranging from ‌425°C to 1350°C‌ (with momentary exposure up to ‌1600°C‌).
• Enhanced designs, such as ‌double water-cooling systems‌ or ‌refractory concrete linings‌, further improve thermal resistance.

‌2. Seal & Structural Design‌

• ‌Triple-offset or quintuple-offset hard-seal‌ design minimizes friction and ensures reliable sealing at high temperatures, with leakage rates ≤1.5%.
• ‌Anti-deformation features‌, such as "I-beam" reinforced discs and floating valve shafts, prevent jamming or cracking under extreme heat.

• 3. Actuation Methods‌

  • Available with ‌pneumatic (Pneumatic), electric (Electric), or manual‌ operation.
  • Electric/pneumatic actuators can be equipped with positioners for precise control (4-20mA signal input).

  ‌4. Applications‌

  • ‌Metallurgy‌: Blast furnace gas, sintering exhaust pipelines.
  • ‌Power Generation‌: Boiler flue gas, desulfurization/denitrification systems.
  • ‌Chemicals/Cement‌: High-temperature dust-laden gas, steam regulation.

  ‌5. Common Issues & Solutions‌

  • ‌Seal failure‌: Caused by deformation or wear at high temperatures—solution: Replace with high-temperature-resistant seals or hard-facing alloys.
  • ‌Actuation jamming‌: Clean ash buildup or replace with deformation-resistant discs.

  For detailed technical specifications (pressure ratings, diameter ranges), refer to product manuals or consult manufacturers.
