Flange Butterfly Valve: Principle, Application And Advantages Introduction
What is flange butterfly valve
Flange butterfly valve is a special kind of butterfly valve, which is characterized by the design of flange connection at both inlet and outlet. This flange is actually a flat surface, which can easily and effectively connect the valve and pipeline to avoid leakage problems. At the end of the pipe where the valve is connected, there are also flanges and holes of the same size. The valve is securely mounted on the piping system by means of bolts and nuts.
Flange Butterfly Valve Working Principle
A flanged butterfly valve is a right-angle rotary valve, which means that the valve disc only needs to be rotated a quarter turn to start or stop the flow of fluid. To open a flanged butterfly valve, the handle or handwheel is rotated counterclockwise a quarter turn. This rotational motion is transmitted to the valve disc through the handwheel. The valve disc maintains a synchronized motion with the piping, thus creating an unobstructed path for fluid flow.
To close a flanged butterfly valve, the handwheel is rotated one-quarter turn in the opposite direction (clockwise) from when it was opened. This causes the valve disc to rotate in the opposite direction so that it is perpendicular to the pipeline, thus stopping any fluid flow that tries to pass through the valve.
When throttling with a flanged butterfly valve, the handwheel is simply rotated slightly so that the angle is less than 90 degrees. This allows a certain amount of fluid to pass through the valve, allowing for flow control.
Applications of Flanged Butterfly Valves
- Flanged butterfly valves are used in steam power plants.
- Flanged butterfly valves are used in mining.
- Flanged butterfly valves are used in food and beverage processing plants because they are easy to clean.
- Flanged butterfly valves are also used in the manufacture of pharmaceuticals because they can be cleaned to improve hygiene.
- Flanged butterfly valves are used in municipal water supply and wastewater treatment.
- Flanged butterfly valves are used for fire protection.
- Flanged butterfly valves are used in the manufacture of paper and pulp.
- Flanged butterfly valves are used in the refining of petroleum products.
- Flanged butterfly valves are used for manufacturing different chemicals.
- Flanged butterfly valves are used in heating ventilation and air conditioning systems.
Advantages of flange butterfly valve
- Flanged butterfly valves can be operated manually or automatically.
- Compared with gate valves, check valves and globe valves, flanged butterfly valves are small in size and light in weight.
- Flanged butterfly valves are compact and simple in design.
- Depending on the seat material, flanged butterfly valves can be used in high pressure and high temperature applications.
- Flanged butterfly valves have no fluid leakage.
- Unlike other large valves, flanged butterfly valves can be installed where space is limited.
- Flanged butterfly valves are used to shut off and throttle fluid flow applications.
- Flanged butterfly valves operate by quarter-turn, which makes flanged butterfly valves very fast to operate.
- Flanged butterfly valves are easy to install, clean and maintain.
