Metal hard seal flange butterfly valve
Butterfly Valve features bi-directional sealing with zero leakage and low torque. The metal-seated valve design makes it suitable for a wide range of harsh operating conditions. The eccentric design allows the sealing surfaces to disengage when the valve is opened, reducing seat friction and significantly extending the valve's service life. Additionally, it has inherent fire-safe properties, making it widely used in fluid shut-off and regulation in various pipelines. The triple eccentric butterfly valve follows the API 609 standard.
蝶阀具有双向密封、零泄漏和低扭矩的特点。金属阀座设计使其适用于各种严苛的工况。偏心设计使得阀门开启时密封面能够分离，从而降低阀座摩擦，显著延长阀门的使用寿命。此外，它还具有防火性能，因此广泛应用于各种管道的流体切断和调节。三偏心蝶阀符合API 609标准。
