Triple Eccentric Multi-Layer Fluoroplastic Sealed Butterfly Valve

Overview:

The Triple Eccentric Multi-Layer Fluoroplastic Sealed Butterfly Valve is designed for high-performance sealing in corrosive environments. The unique triple eccentric structure combined with a multi-layer fluoroplastic seal provides excellent corrosion resistance, reliable sealing, and long service life, making it ideal for handling aggressive chemicals and high-pressure applications.

Product Features:

1. Triple Eccentric Structure:
   • First Eccentricity: The stem is positioned behind the centerline of the sealing surface, which reduces friction during opening and closing, extending the valve’s lifespan.
   • Second Eccentricity: The stem is offset from the pipe’s centerline, allowing the valve disc to rotate freely without rubbing against the seat, reducing wear.
   • Third Eccentricity: The conical design of the sealing surfaces eliminates friction between the disc and seat during operation, providing smooth movement and effective sealing.
2. Multi-Layer Fluoroplastic Seal:
   • Fluoroplastic Material: The seal is made from high-performance fluoroplastic materials such as PTFE or FEP, which offer excellent resistance to corrosive chemicals, acids, and alkalis.
   • Durability and Chemical Resistance: The multi-layer design ensures a strong, leak-tight seal even in harsh chemical environments, providing high resistance to chemical attack and ensuring long-term durability.
   • Low Friction: Fluoroplastic materials have low friction coefficients, ensuring smooth operation and reducing the required torque for valve actuation.
3. Corrosion-Resistant Construction:
   • The valve body and disc can be made from materials like stainless steel or alloy steel, combined with fluoroplastic coatings or linings to provide maximum corrosion resistance in aggressive environments.
   • This makes the valve suitable for applications involving corrosive fluids, gases, and high-temperature processes where metal seals may not perform effectively.
4. Superior Sealing Performance:
   • Zero Leakage: The triple eccentric design combined with the fluoroplastic seal ensures zero leakage, making the valve suitable for critical applications requiring tight shut-off in both flow directions.
   • Bidirectional Sealing: The valve can provide tight sealing in both directions, ensuring operational safety and reliability in fluctuating pressure environments.
   • High Pressure and Temperature Capability: The valve can handle high pressure (up to PN25) and moderate temperature ranges, depending on the material composition.
5. Operational Benefits:
   • Low Torque Operation: The triple eccentric structure significantly reduces friction between the disc and seat, lowering the required torque for operation and enabling the use of smaller actuators.
   • Quick Operation: As a butterfly valve, it offers rapid opening and closing, providing efficient flow control and minimizing downtime in industrial processes.
   • Easy Maintenance: The valve’s design allows for easy maintenance, with replaceable seals and seats that simplify servicing, reducing overall operational costs.
6. Applications:
   • Chemical Processing: Ideal for handling highly corrosive fluids such as acids, alkalis, and solvents in the chemical and pharmaceutical industries.
   • Water Treatment: Suitable for use in wastewater treatment plants where resistance to corrosive chemicals is essential.
   • Petrochemical Industry: Widely used in refineries and chemical plants for managing aggressive media, including sour gas and crude oil.
   • Food and Beverage: Safe for use with corrosive cleaning agents and fluids in food processing facilities, where hygienic conditions are required.
   • Pulp and Paper: Perfect for controlling the flow of corrosive chemicals used in pulp and paper production processes.
7. Pressure and Temperature Ratings:
   • Pressure Rating: The valve is typically rated for pressures ranging from PN10 to PN25, depending on the size and material.
   • Temperature Range: Suitable for moderate temperature ranges, generally between -40°C to 200°C, depending on the selected fluoroplastic material.
8. Connection Types:
   • Flanged Connection: Available with flanged ends for secure connection to the pipeline, ensuring a leak-proof installation.
   • Wafer and Lug Designs: The valve can also be supplied in wafer or lug types, allowing for easy installation between pipeline flanges.

Advantages:

• Exceptional Corrosion Resistance: The fluoroplastic seal provides superior resistance to aggressive chemicals, making the valve ideal for use in harsh environments.
• High Sealing Efficiency: The multi-layer seal and triple eccentric design ensure a tight, reliable shut-off, minimizing the risk of leaks.
• Low Operating Costs: With reduced friction and wear, the valve requires less maintenance and offers a long service life, which helps reduce operating costs.
• Wide Range of Applications: Suitable for a variety of industrial applications, including chemical processing, water treatment, and other industries requiring corrosion-resistant valves.

Conclusion:

The Triple Eccentric Multi-Layer Fluoroplastic Sealed Butterfly Valve offers reliable performance and superior corrosion resistance, making it an ideal solution for demanding industrial applications involving aggressive media. With its advanced triple eccentric structure, durable fluoroplastic seal, and bidirectional tight shut-off capabilities, this valve ensures optimal efficiency, long service life, and low maintenance, meeting the stringent requirements of chemical, petrochemical, and water treatment industries.
