Product Description

‌High-Temperature Flue Gas Butterfly 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.
