A butterfly valve is a quarter-turn valve, turning 90 degrees. A butterfly valve is a disk-form connected to a rod that opens and closes the directional flow when the rod rotates the disc. Anix Butterfly Valves is a quarter-turn rotational motion valve to regulate the flow.
Where are butterfly valves used?
Buttery valves are used in various process media and industries, especially in:
- Water supply
- Water Collection
- Water distribution
- Pumping stations
Also, it is used in a broad range of use cases, especially in flow isolation. The simple construction and compactness of buttery valves don’t affect the weight because it has a lighter weight and is affordable.
Parts of a butterfly valve
There are major components of a butterfly valve, such as:
- Valve body. The valve body will fit between the pipe flanges. There are most common end connection types, such as:
- Double Lug
- Disc. It is attached to the valve body that functions as a gate, it stops or throttles the fluid flow. It is equivalent to the gate in a gate valve. There are some variations of the disc’s factors, such as:
The factors of the disc help improve flow, seal, and operate torque.
- Seat. It is in line with the internal valve body, it has a strong metal anti-leak seal or elastomer that secures the disc in the closed position to achieve a complete shutoff.
- Stem. The valve shaft is also called the stem, a component connecting the disc to the actuation mechanism and it transmits the torque through itself.
- Seals. It is present at several interfaces in the valve to ensure a tight seal while in operation or isolating the process media from the internal component of the valve for a more flexible and cost-efficient design.
Butterfly valve type
Butterfly valves are essential in applications where tight shut-off is necessary. The disc will open and close with a low-torque rotation and works for a compatible application. It tends to cost less and lighter weight, so there are different types of butterfly valve types to choose from, such as:
- Zero offset
- Double offset
- Triple offset
Butterfly valves come in various designs and materials specific to the systems involved. These are recognised in the market for some reasons, such as:
- Excellent flow and control characteristics
- Tight sealing capabilities
