A butterfly valve can be used to control flow in any direction with just a quarter turn of the handle. The disc of a butterfly valve is turned by a splined shaft. The line is completely cut off when the butterfly valve
A butterfly valve is a quarter-turn valve that can be used for isolating or regulating flow of a fluid. The closing mechanism takes the form of a disk. Butterfly valves are generally favored because they are lower in cost than other types of valves and because they have low operating torque and require very less auxiliaries to operate. They are installed between flanges at both ends of the pipeline.
Advantages of butterfly valves
Butterfly valves offer many advantages over other types of valves, some of which are listed below:
- First of all, the butterfly valve is easy to install. Because the butterfly valve body and the two halves of the butterfly valve are integrated, it is not necessary to connect the two halves of the butterfly valve with bolts when the butterfly valve is installed, which is more convenient to install.
- Secondly, the butterfly valve saves space. Its body and the two halves are integrated, and then it only needs to be installed on the pipeline, so it does not need to occupy a lot of space.
- Thirdly, the butterfly valve can be used in various positions. Its body and the two halves of the butterfly valve are integrated, and then it can be installed in any position on the pipeline.
- Fourth, it can be used in water supply and drainage, oil and gas, food and beverage, chemical industry, pharmaceutical industry, power industry, and other industries.
Disadvantages of the butterfly valve
Butterfly valves have the following disadvantages:
- They are not suitable for use in the pipeline where the medium pressure is very high
- They are not suitable for use in the pipeline where the medium temperature is very high
- They are not suitable for use in the pipeline where the medium contains particles or fibers
- They are not suitable for use in the pipeline where the medium viscosity is very low
- They are not suitable for use in the pipeline where the medium is flammable and explosive
Butterfly valves are installed in lines with frequent operation demand. The application of the butterfly valve is very broad – it is used in all phases of production, transportation, and distribution of oil, gas, water, chemicals, pharmaceuticals, food, beverages, paper, textile, etc.
Butterfly valves are used in many different industries for a variety of purposes. Here are some of the most common applications for butterfly valves:
- Used in piping systems to control the flow of fluids
- Used in HVAC systems to regulate the flow of air
- Used in the food and beverage industry to control the flow of liquids and gases
- Used in the pharmaceutical industry to control the flow of liquids and gases
- Used in the chemical industry to regulate the flow of corrosive liquids
