Triple Eccentric Hard-Sealed High-Temperature Butterfly Valve
Product Overview
The Triple Eccentric Hard-Sealed High-Temperature Butterfly Valve is a critical valve designed for regulating and isolating media within high-temperature pipelines in the refining industry. Engineered for extreme service, it excels in demanding applications with its superior performance in high-temperature resistance, wear and corrosion resistance, rapid actuation, high sensitivity, and zero leakage.
Key Features & Advantages
- Exceptional High-Temperature Performance: Reliably operates in environments with temperatures up to 750°C, maintaining structural integrity and sealing performance.
- Zero Leakage & Hard Seal: Features a triple-eccentric design with a hard metal seat, ensuring bubble-tight shut-off (ANSI B16.104 Class V) even after prolonged cycling.
- Abrasion & Corrosion Resistant: Specifically designed to handle erosive media such as high-temperature flue gas containing trace catalyst particles.
- Rapid & Precise Operation: Offers quick opening and closing action with high control sensitivity, ideal for precise flow regulation.
- Robust & Durable Construction: Built to stringent standards for long-term, maintenance-free service in critical refining processes.
