“aira” high-performance triple eccentric butterfly valves feature metal-to-metal seating for both throttling and isolation applications. They offer bi-directional flow control, zero leakage, and low fugitive emissions. Suitable for extreme temperatures (up to 550°C and down to -196°C), these valves use a triple offset design to eliminate friction and ensure a snug, high-performance seal. The laminar seal with grafoil layers adapts to temperature changes, maintaining a uniform wedging effect and preventing leakage.
