1. Butterfly valves feature simple structure, small 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 sealing performance.

2. Butterfly valves can transport slurry, with minimal liquid accumulation at the pipe mouth. They achieve good sealing under low pressure and have excellent regulating performance. Thank you.

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

4. The valve stem is a through-rod structure, tempered for good comprehensive mechanical properties, corrosion resistance, and anti-scratch performance. During valve operation, the stem only rotates without lifting, so the stem packing is less prone to damage, ensuring reliable sealing. Fixed with the butterfly plate via a taper pin, the extended end is designed to prevent blowout, avoiding accidental stem ejection if斷裂 occurs at the connection.

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

Driving forms include manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic linkage actuators, enabling remote control and automated operation.
