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.

FAQ’s
Have a question before you buy our products? Take a look at the FAQs below.
If you don’t find the answer you’re looking for, get in touch with us here.
- What is a Lined Butterfly Valve?
- How does it work?
It operates by rotating a disc within the flow path to control the flow of fluid. The lining material ensures a smooth and corrosion-resistant surface for fluid contact, while the disc regulates flow by either blocking or allowing passage through the valve.
- What are the main applications?
Lined Butterfly Valves are commonly used in industries such as chemical processing, petrochemical, pharmaceutical, water treatment, and pulp and paper for handling corrosive and abrasive fluids.
- What are the benefits of using one?
The benefits include excellent corrosion resistance, chemical compatibility, reliable sealing, low maintenance, and suitability for a wide range of applications.
- What materials are used in their construction?
Lined Butterfly Valves are typically constructed with a metal body and a lining material such as PTFE, PFA, FEP, PVDF, or polypropylene to provide corrosion resistance.
- How do I choose the right one for my application?
Consider factors such as the type of fluid, temperature range, pressure rating, valve size, end connections, and compatibility with specific application requirements to select the appropriate lined butterfly valve.
- Can they be repaired?
Yes, lined butterfly valves can be repaired by replacing damaged components such as the lining material, disc, or seals as needed.
- What maintenance is required?
Regular maintenance includes inspection, cleaning, and lubrication of moving parts to ensure smooth operation and prevent corrosion or damage to the lining material.
- Are they available in different designs?
Yes, lined butterfly valves are available in various designs, including wafer, lug, and flanged configurations, as well as different lining materials and actuation options to suit different application needs.
