The role of butterfly valve in pipeline

The butterfly valve plays a crucial role in pipeline systems by regulating, isolating, and controlling the flow of fluids (liquids, gases, or slurries). Here's a breakdown of its roles:

1. Flow Control

The butterfly valve disc rotates to allow partial or full opening, adjusting the flow rate as needed.

Ideal for throttling applications due to its quick operation.

2. Shut-off/Isolation

In the closed position, the disc blocks the flow completely, effectively isolating sections of the pipeline for maintenance or safety.

3. Quick Operation

A simple 90° turn of the handle or actuator opens or closes the valve, making it suitable for fast flow control in automated systems.

4. Space- and Cost-Efficiency

Compact and lightweight, making it easier and cheaper to install compared to other valve types like gate or globe valves.

5. Versatility

Can handle various media, including water, steam, air, oil, and corrosive chemicals—widely used in water treatment, HVAC, chemical plants, and food processing.
