What are Lined Butterfly Valves?

Lined butterfly valves are a type of butterfly valve that has a lining on the inside of the valve body. The lining is typically made of a material that is resistant to corrosion, such as PTFE, PFA, or FEP. Lined butterfly valves are used in applications where the fluid being conveyed is corrosive or abrasive.

How do Lined Butterfly Valves Work?

PTFE, PFA, FEP, PVDF Lined butterfly valves work in the same way as standard butterfly valves. The valve has a disc that is attached to a stem. When the stem is rotated, the disc rotates and opens or closes the valve. The lining on the inside of the valve body helps to protect the valve from corrosive or abrasive fluid.

Features of PTFE, PFA, FEP, PVDF Lined Butterfly Valves

Corrosion resistance: Lined butterfly valves are resistant to corrosion because of the lining on the inside of the valve body. This makes them ideal for use in applications where the fluid being conveyed is corrosive.

Abrasion resistance: Lined butterfly valves are also resistant to abrasion because of the lining on the inside of the valve body. This makes them ideal for use in applications where the fluid being conveyed is abrasive.

Easy to operate: Lined butterfly valves are easy to operate. They can be opened and closed quickly and easily, even under pressure.

Wide range of sizes and materials: Lined butterfly valves are available in a wide range of sizes and materials. This allows you to choose the right valve for your specific application.

Applications of Lined Butterfly Valves

Lined butterfly valves are used in a variety of applications, including:

Chemical processing: Lined butterfly valves are used in the chemical processing industry to control the flow of corrosive chemicals.

Oil and gas: Lined butterfly valves are used in the oil and gas industry to control the flow of corrosive fluids.

Water treatment: Lined butterfly valves are used in the water treatment industry to control the flow of corrosive water.

Power generation: Lined butterfly valves are used in the power generation industry to control the flow of corrosive fluids.

HVAC: Lined butterfly valves are used in the HVAC industry to control the flow of corrosive fluids.
