1. Butterfly valves feature simple structure, compact size, light weight, low material consumption, small installation dimensions, quick switching, 90° reciprocating rotation, and low driving torque. They are used to cut off, connect, and regulate the medium in pipelines, offering excellent fluid control characteristics and tight sealing performance.

2. Butterfly valves can transport slurry with minimal liquid accumulation at the pipe orifice. They provide good sealing under low pressure and offer excellent regulating performance. Thank you.

3. The streamlined design of the butterfly disc minimizes fluid resistance loss, making it an energy-efficient product.

4. The valve stem is a through-rod structure, heat-treated to achieve good comprehensive mechanical properties, corrosion resistance, and anti-scratch performance. During valve operation, the stem only rotates without lifting, preventing damage to the stem packing and ensuring reliable sealing. It is fixed to the butterfly disc with a taper pin, and the exposed end is designed to prevent blowout, avoiding accidental ejection in case of fracture at the stem-disc connection.

5. Connection methods include flange connection, wafer connection, butt weld connection, and lug wafer connection.

Actuation forms include manual, gear transmission, electric, pneumatic, hydraulic, and electro-hydraulic actuators, enabling remote control and automated operation.
