Double Eccentric Butterfly Valve

The Mecco triple eccentric butterfly valve features bidirectional zero leakage and low torque. The metal-seated sealing structure makes it suitable for various harsh operating conditions. Its eccentric design ensures that the sealing pair disengages instantly upon opening, minimizing seat friction and significantly extending valve service life. It also provides inherent fire-safe characteristics. The Mecco triple eccentric butterfly valve adopts an eccentric design and complies with API 609 standards.

The Mecco double eccentric butterfly valve features an elastic pressure self-sealing seat structure that enables bidirectional zero leakage and achieves lower torque, thereby reducing actuator procurement costs. Its cam-effect sealing structure separates the valve seat from the disc after a certain opening angle, reducing friction and greatly extending service life. It is widely used for shut-off and regulation of pipeline fluids. The Mecco double eccentric butterfly valve adopts an eccentric design and complies with API 609 standards.

The Mecco soft-sealing resilient seated centerline butterfly valve offers both shut-off and flow regulation functions. It is widely used for various industrial fluid control applications. The fully rubber-lined valve body ensures complete isolation from the medium, making it suitable for various corrosive working conditions. Compared to traditional gate valves, globe valves, and ball valves, it is lighter in weight and more cost-effective. With the rapid development of the synthetic rubber industry, soft-sealing resilient seats are not only used in traditional water treatment but also in various modern chemical industries. The Mecco centerline butterfly valve adopts a concentric design and complies with API 609 standards.
