Bi-Directional Triple Eccentric Metal Hard-Seal Butterfly Valve, Butt-Welded Type

Triple eccentric butterfly valve features bi-directional sealing with zero leakage and low operating torque.

The metal seal seat enables the valve to perform in various severe working conditions.

Its eccentric design allows the sealing pair to disengage instantly when the valve opens, minimizing seat friction and greatly extending service life.

The valve also has inherent fire-safe properties and is widely used for isolation and regulation of fluids in pipelines.

Our triple eccentric butterfly valves adopt an eccentric design and comply with API 609.
