PTFE Butterfly Valve

The PTFE butterfly valves are available in two versions, i.e. fully lined PTFE butterfly valve and PTFE seat butterfly valve. Fergo also offers a PTFE-seated butterfly valve with an EPDM support ring. The application of PTFE butterfly valves is suitable for use in corrosive media such as acids, where rubber seats such as EPDM, NBR and FPM-Viton are less suitable.

What Makes PTFE Butterfly Valves Special?

Polytetrafluoroethylene (PTFE) is a fluoropolymer that is highly valued in industrial settings for its unique properties. PTFE-coated butterfly valves are particularly renowned for their durability and versatility across challenging applications. Here's a closer look at the unique features of PTFE butterfly valves:

01/

Exceptional Chemical Resistance
PTFE is virtually inert, which means it does not react with most chemicals. This property makes PTFE butterfly valves incredibly useful in industries where corrosive liquids or gases are processed. Whether it’s strong acids, bases, solvents, or various organic compounds, PTFE ensures that the valve's functionality and integrity are not compromised, thus maintaining safety and process purity.

02/

High-Temperature Tolerance
PTFE can withstand temperatures ranging from -100°F to 500°F (-73°C to 260°C). This broad temperature range allows PTFE butterfly valves to be employed in processes involving extreme heat, such as steam systems or applications requiring cold resistance like cryogenic processes. The ability to operate under such temperature extremes without degrading adds to the valve’s reliability and lifespan.

03/

Low Friction Coefficient
PTFE’s low coefficient of friction not only prevents materials from sticking to the valve components but also reduces wear and tear during operation. This characteristic is particularly beneficial in applications where the valve must operate frequently or under high-speed conditions, ensuring smooth operation and reducing maintenance needs.

04/

Enhanced Sealing Capabilities
PTFE’s flexibility, despite its strength, allows it to conform to sealing surfaces better than many harder materials. This adaptability ensures a tighter seal and reduces the potential for leaks, which is crucial in maintaining system efficiency and preventing contamination and environmental harm.

Performance Advantages

Lightweight

Easier to handle and install compared to other valve types.

Low-Pressure Drop

Minimizes energy loss during flow.

High-Pressure Recovery

Efficiently restores system pressure after flow restriction.

Customization

Another good thing about PTFE valves is they can be customized for different uses. Manufacturers offer various sizes ranging from 2 to 24 inches. Each size suits different flow requirements and pie dimensions. Therefore, even when the market doesn’t have specific measurements, you only need to contact a manufacturer with your dimensions.

Applications

Chemical and petrochemical industries

Acid and alkali distribution systems

Water and wastewater treatment

Pharmaceutical and cosmetic production

Pulp and paper processing

Food and beverage flow lines

How Does Ptfe Lined Butterfly Valve Work

The PTFE lined butterfly valve operates based on the quick shut off principle. The circular disc (butterfly) of the PTFE lined butterfly valve is placed in the center of the pipe which allows a rod to go through it to an actuator, on the outer side of the PTFE lined butterfly valve. Using the handwheel, the metal disc is rotated to keep the disc parallel or perpendicular to the flow and it allows or closes the flow. So, the operating principle of the PTFE lined butterfly valves is fairly simple.

The PTFE lined butterfly valve is one of the few industrial valves that are both efficient in isolating and regulating the flow of media. The PTFE lined butterfly valve is also quick to open. The disc is attached to the stem, either through the former or the stem is at the back of the disc. The stem is attached to the handle that is either placed on top of the body or at its side.
