Full Body Lining Butterfly Valves are a type of industrial valve used to control the flow of fluids (liquids or gases) through pipes or ducts. They are commonly used in various industries, including chemical processing, water treatment, power generation, and oil and gas.
The term "full body lining" refers to the construction of the valve, where the interior surfaces that come into contact with the flowing fluid are lined with a corrosion-resistant or erosion-resistant material. This lining helps protect the valve from the potentially harsh or corrosive nature of the fluids being transported, extending the valve's lifespan and ensuring reliable operation.
The primary components of a full body lining butterfly valve include:
Body: The outer casing of the valve, typically made of a sturdy material such as cast iron, ductile iron, or carbon steel. The interior of the body is lined with a material that can withstand the corrosive or erosive properties of the fluid.
Disc or Plate: This is the component that controls the flow by rotating within the valve body. The disc is also lined with the same material as the body lining.
Seat: The seat is the sealing surface that the disc or plate comes into contact with when the valve is in the closed position. Like the other components, the seat is lined with a corrosion-resistant material.
Lining Material: The lining material used in full body lining butterfly valves can vary depending on the specific application and the type of fluid being transported. Common lining materials include PTFE (polytetrafluoroethylene), rubber, neoprene, EPDM (ethylene propylene diene monomer), and more.
The advantages of using full body lining butterfly valves include:
Corrosion Resistance: The lining material provides protection against corrosion, making the valve suitable for handling corrosive fluids.
Erosion Resistance: These valves are also effective at withstanding erosive forces caused by the flow of abrasive fluids.
Reduced Maintenance: The lining helps extend the valve's lifespan, reducing the need for frequent maintenance and replacement.
Wide Applicability: Full body lining butterfly valves can be used in a variety of industries and applications, thanks to their resistance to various fluids and corrosive environments.
It's important to note that while full body lining butterfly valves offer significant benefits, they may also come with some limitations, such as potential temperature and pressure restrictions based on the chosen lining material. Proper selection and maintenance of the valve are essential to ensuring its reliable performance and longevity.
