What is the advantage of butterfly valve?

1. Cost-effective: Butterfly valves are typically less expensive than other types of valves, such as gate valves or ball valves. This makes them an attractive option for applications where cost is a major consideration.

2. Low torque: Butterfly valves require less torque to operate than other types of valves, making them easier to actuate and reducing the need for large, heavy-duty actuators.

3. Compact design: Butterfly valves have a compact design, which means they require less space for installation than other types of valves. This can be particularly beneficial in applications where space is limited.

4. Quick operation: Butterfly valves can be operated quickly, as the disc rotates around its axis to open or close the valve. This makes them ideal for applications where rapid operation is required.

5. Low pressure drop: Butterfly valves typically cause less pressure drop across the valve than other types of valves, such as globe valves. This means that less energy is required to pump fluid or gas through the valve.

6. Easy to maintain: Butterfly valves have a simple design with fewer components than other types of valves, making them easy to maintain and repair.

Overall, the advantages of butterfly valves make them a popular choice for a wide range of applications, including water treatment, HVAC, chemical processing, and more.
