Triple Eccentric Butterfly Valve
High Performance • Durable • Leak Proof
Metal-seated triple eccentric butterfly valve designed for reliable isolation in demanding industrial pipelines.
Technical Specifications
Key Features & Applications
A Triple Eccentric Butterfly Valve is designed for industrial pipelines where tight sealing, high temperatures and repeated operation are important. Unlike conventional butterfly valves, it uses three offsets in the disc and shaft arrangement. This geometry allows the disc to move away from the seat during opening, reducing friction between the sealing surfaces and limiting wear over time.
The valve typically uses a metal-to-metal or laminated metal sealing arrangement, making it suitable for demanding operating conditions. Its quarter-turn design provides straightforward opening and closing, while the offset construction helps maintain sealing performance during frequent operation.
