Designed with a triple eccentric structure, the valve completely avoids friction between sealing surfaces during opening and closing. The precision metal hard seal pair achieves bidirectional zero leakage. Its sealing stability is not affected by high temperature, high pressure and fluctuating pressure difference, ensuring long-term reliable tight shutoff under harsh industrial conditions.

Adopting high-strength metal hard seal configuration, this valve features outstanding resistance to high temperature, high pressure, erosion and abrasion. It can stably handle complex media such as high-temperature steam, flue gas, heat conduction oil and particle-containing fluid. It is far more adaptable to severe working conditions than ordinary soft-seal butterfly valves.

The friction-free opening and closing design effectively reduces wear on core components and greatly extends the valve’s service life. It requires low operating torque, supports frequent switching and continuous long-term operation. With stable overall structure and low failure rate, it minimizes daily maintenance work.
