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).
