Butterfly Valve

1.Product Overview​​

Butterfly valves are quarter-turn rotational motion valves designed for reliable flow control in industrial piping systems, featuring a circular disc that rotates 90° to regulate media flow.

​​Key Advantages​​

✔ ​​Compact & Lightweight​​ - 30-50% lighter than gate valves

✔ ​​Quick Operation​​ - 90° rotation enables fast open/close

✔ ​​Low Pressure Drop​​ - Streamlined disc design minimizes flow resistance

✔ ​​Cost-Effective​​ - 40-60% lower cost than equivalent ball valves

✔ ​​Versatile​​ - Suitable for liquids, gases, and slurries
