A Butterfly valve is a quarter-turn rotating motion valve, that is utilized to prevent, control, and start flow. It contains a disc that is attached to a revolving shaft. When the butterfly valve is fully sealed, the disk blocks the line.
The butterfly valve contains only four main modules: body, disk, stem, and seat. Butterfly valve needs less material due to their design. They are normally very easy, fasten to open, and delivers a comprehensive closure or opening of the valve. They are comparatively cheap to construct and needless material due to their design.
The following are some typical applications of Butterfly valves:
- Cooling water, air, gases, fire protection, etc.
- Slurry and similar services
- Vacuum service
- High-pressure and high-temperature water and steam services
- Compressed air or gas applications
At Speciality valves, we manufacture butterfly valves that have fewer space requirements and are generally associated with reduced maintenance. They can perform well in large volume water and slurry applications.
Types of Butterfly Valve:
- Wafer Butterfly Valve
- Lug Butterfly Valve
- Double Flanged Butterfly Valve
- Triple Offset Butterfly Valve
