I. Structure and Performance Introduction of Electric Flanged Hard-sealed Butterfly Valve
This product is composed of main components such as the valve body, disc, sealing ring, and transmission mechanism. Its structure is designed based on the three-dimensional (triple) eccentric principle, adopting a new compatible processing technology of elastic sealing and hard/soft multi-layer sealing. This reduces the torque during the operation of the butterfly valve, achieving labor-saving and energy-saving functions, thereby ensuring the overall reliability of corrosion resistance, high-temperature resistance, and wear resistance.

II. Main Performance Features

1. Unique structure, compact and lightweight, flexible operation, labor-saving and convenient.

2. Reliable sealing, achieving gas-tight zero leakage.

3. Flow characteristics tend to be linear with excellent regulating performance.

4. Adopts the triple-offset principle, resulting in nearly zero wear on the sealing surfaces and extending the valve's service life.

5. Wide application range. For example: suitable for media such as water, steam, oil, air, and gas.

6. Suitable for various temperatures and pressure ratings up to 6.4 MPa, with corrosion resistance for various media pipelines.

III. Application
This butterfly valve is suitable for flow regulation and fluid shut-off devices in food, pharmaceutical, petrochemical, power plants, steel plants, industrial environmental protection water treatment, high-rise buildings, water supply and drainage pipelines.
