🔍 What Is a Double Flanged Butterfly Valve?
Structure and Design
A double flanged butterfly valve generally includes:
- Valve body with double flange ends
- Rotating valve disc
- Sealing seat
- Stem shaft
- Manual or automated actuator
The double flange structure provides strong pipeline installation support.
Working Principle
The valve regulates fluid flow through disc rotation:
- Open position allows fluid flow
- Closed position blocks the pipeline
This quarter-turn operation enables efficient and reliable flow control.
