What are PTFE / FEP / PFA 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 PTFE / FEP / PFA Lined Butterfly Valves Work?

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 / FEP / PFA 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: PTFE / FEP / PFA  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.

If you don’t find the answer you’re looking for, get in touch with us here.

  • What is a butterfly valve?

    A butterfly valve is a type of quarter-turn valve that uses a disc or plate, known as a butterfly, to control the flow of fluid within a pipeline. The disc is positioned perpendicular to the flow in the closed position and rotates 90 degrees to allow full flow in the open position.

  • Are Butterfly Valves safe?

    Butterfly Valves are one of the safest valves to use. It works very well in high temperature and high-pressure services, making it safe for all types of use. At Freture, all our valves are manufactured as per international standards. Are 100% leak-proof and emission free. Saves down-time and process media. Maintenance free. Easy to install and remove.

  • How Do Butterfly Valves Work?

    When the disc is in the open position, it allows fluid to flow through the valve. When the disc is in the closed position, it blocks the flow of fluid. The disc is typically rotated by a handwheel or a pneumatic or electric actuator

  • What are the advantages of Butterfly Valves?

    There are three main types of butterfly valves:

    • Wafer butterfly valves: These valves have a wafer-like body that fits between two flanges, allowing them to be installed in pipelines without additional support.
    • Lug butterfly valves: Lug butterfly valves have threaded inserts on both sides of the valve body, enabling them to be bolted onto the pipeline.
    • Double-flanged butterfly valves: These valves have flanges on both ends of the body, allowing them to be connected directly between pipe flanges.
  • Can Butterfly Valves be used in both liquid and gas applications?

    Yes, Butterfly Valves can be used in both liquid and gas applications. The selection of materials and proper sizing of the valve should be based on the specific characteristics of the fluid or gas being controlled.

  • What maintenance is required for Butterfly valves?

    Regular maintenance for Butterfly Valves includes inspection, lubrication, and periodic testing of the valve components. This helps ensure proper functioning, prevent leakage, and extend the valve's lifespan. Maintenance requirements may vary based on the specific valve design, materials used, and the operating conditions.
