Flanged PTFE Butterfly Valve-A

Product Features and Applications

Structural Features

PTFE Sealing:

The sealing surfaces of the valve body and butterfly plate are usually made of polytetrafluoroethylene (PTFE) or other fluoroplastics. These materials have excellent corrosion resistance, high-temperature resistance, and good anti-adhesion properties, ensuring the long-term stable operation of the valve in corrosive media.

Flanged Connection:

The flanged butterfly valve uses a flanged connection method, with the valve body connected to the pipeline via flanges, providing a secure installation and excellent sealing performance. It is suitable for medium and high-pressure pipeline systems and effectively prevents leakage.

Bidirectional Sealing:

Many flanged butterfly valves are designed with bidirectional sealing, ensuring good sealing performance regardless of the flow direction of the medium, which enhances the versatility of the valve.

Performance Features

Excellent Corrosion Resistance:

The use of fluoropolymer materials for the sealing surfaces and lining allows this butterfly valve to effectively resist corrosion from various aggressive media, such as acids, bases, and salts, making it highly suitable for the chemical and pharmaceutical industries.

Good Sealing Performance:

The flexibility of the fluoropolymer material ensures that the valve can fit tightly when closed, providing reliable sealing under both high and low temperature conditions, thus preventing leakage.

Easy Operation:

The butterfly valve is lightweight and can be quickly opened and closed using manual, pneumatic, or electric actuators, making it ideal for frequent operation scenarios.

Wide Applicability:

Due to its outstanding corrosion resistance and good sealing performance, the multi-standard wafer-type fluoropolymer butterfly valve is suitable for various demanding working conditions, such as in the chemical, pharmaceutical, food, and paper industries.

Application Fields

Chemical Industry:

Widely used in the transportation and control of corrosive media in chemical production, such as acids, alkalis, and salt solutions.

Pharmaceutical Industry:

Suitable for fluid control systems in the pharmaceutical industry that require high cleanliness and corrosion resistance, such as the transportation of various medicinal liquids.

Food Industry:

Used in the food processing industry for the control and transportation of various fluids, with fluoropolymer materials meeting food-grade requirements to ensure safety and prevent contamination.

Paper Industry:

Applicable for the transportation and flow control of corrosive chemicals in the paper production process, ensuring the stability of the production process.

Installation and Maintenance

Easy Installation:

Flanged butterfly valves connect via flanges, requiring alignment with the pipeline flanges and securing with bolts during installation, making the process simple and quick.

Convenient Maintenance:

The valve’s structural design is straightforward, allowing for easy daily maintenance. Regularly checking the sealing components and lubricating the valve stem can ensure long-term normal operation.

Regular Inspections:

It is recommended to regularly check the condition of the fluoropolymer seals and promptly replace any worn or aged seals to ensure the long-term reliability of the valve.
