Product Features
▶Corrosion and Wear Resistance: The fluorine-lined butterfly valve is engineered for high-purity and non-contaminating applications, providing outstanding resistance to corrosion and wear. The fluoropolymer lining, typically made from PTFE or PFA, ensures that the valve body remains protected when exposed to aggressive chemicals, acids, and high-temperature media. This durability extends the valve's lifespan, reducing maintenance costs and downtime.
▶Leakage Protection and Pollution Prevention: The valve features a robust O-type elastic diaphragm seat with a flexible lip design, offering superior sealing capabilities. This innovative design ensures no internal leakage, even under high-pressure conditions, while also preventing pollution from affecting the environment. The self-compensating design further enhances sealing integrity over time, making it ideal for industries that demand purity and reliability.
▶Enhanced Maintenance and Servicing: The valve body utilizes a two-piece butterfly plate structure combined with an eccentric shaft and segmented design. This configuration not only ensures smooth operation but also allows for easy maintenance. The valve seat is both replaceable and adjustable, making it straightforward to service, reducing operational interruptions and extending the service life of the valve.
▶Versatile Actuation Options: Designed with flexibility in mind, the fluorine-lined butterfly valve comes equipped with an ISO standard mounting pad. This feature allows the valve to be easily fitted with various actuation methods, including pneumatic, electric, hydraulic, and electro-hydraulic actuators. This adaptability ensures seamless integration into automated systems, offering optimal control for diverse applications.
▶Multiple Actuation Methods: The valve can be manually operated or equipped with a range of actuation options, including pneumatic, electric, hydraulic, and electro-hydraulic systems. These actuation methods provide users with flexibility in valve control, allowing the valve to be used in both manual and automated applications across various industries such as chemical processing, water treatment, and power generation.
Application Recommendations
▶Chemical Processing: Ideal for handling aggressive chemicals, acids, and bases, the fluorine-lined butterfly valve ensures reliable operation in environments where corrosion resistance is crucial.
▶Pharmaceutical Industry: Its non-contaminating design makes it perfect for maintaining the purity of sensitive materials in pharmaceutical manufacturing processes.
▶Water Treatment: The valve is well-suited for managing corrosive chemicals in water treatment systems, ensuring efficient flow control while maintaining system integrity.
▶Power Generation: Designed to manage corrosive media in power plants, this valve offers durability and secure sealing for critical applications in energy production.
