What Is The Cast Iron Fluorine Flange Pneumatic Butterfly Valve？
The cast iron fluorine flange pneumatic butterfly valve is engineered for rigorous industrial environments demanding reliable performance amidst corrosive conditions. Its cast iron body, complemented by a fluorine-lined interior, ensures exceptional resistance to corrosive substances like acids and alkalis. Featuring a flanged connection, this valve allows for easy installation onto piping systems, guaranteeing a secure seal to prevent leaks.
Moreover, its pneumatic actuator facilitates remote operation, granting precise control over fluid flow rates and process parameters. This valve stands as a robust and versatile solution across sectors such as chemical processing and petrochemical industries, where corrosion resistance and dependable performance are paramount in fluid handling systems.

The Cast Iron Fluorine Flange Pneumatic Butterfly Valve offers a multitude of features and benefits:
Versatility: Designed to handle a wide range of corrosive substances, including acids, alkalis, salts, oxidants, reductants, organic solvents, and various other media. This versatility makes it suitable for diverse industrial applications.
Actuator Options: Available with both spring return and double return actuators, providing flexibility in operation and allowing for precise control over the valve’s opening and closing mechanisms.
Superior Corrosion Resistance: The valve’s fluorine-lined construction ensures excellent resistance to corrosion, even in highly aggressive environments. This makes it an ideal choice for industries where corrosion is a significant concern, such as chemical processing, petrochemical, and pharmaceutical industries.
Reliable Performance: Built to withstand the demands of industrial operations, the valve offers reliable performance over an extended service life. Its robust construction and high-quality materials contribute to its durability and long-term functionality.
Ease of Maintenance: Designed for ease of maintenance, the valve features a simple and accessible design that facilitates inspection, cleaning, and repairs. This helps minimize downtime and ensures optimal performance throughout its lifecycle.
Safety: The valve’s reliable performance and corrosion resistance enhance safety in industrial processes, reducing the risk of leaks, spills, and accidents associated with corrosive substances. Additionally, its precise control capabilities contribute to safer and more efficient operation.
Technical Parameters of Butterfly Valves：
Air source processor: The pneumatic triplet, a vital accessory for pneumatic valves, combines filtering, pressure reduction, and lubrication functions. The pressure reducing valve adjusts inlet pressure to a stable outlet pressure, utilizing the medium’s energy. In two-piece assemblies, it couples with a filter for compressed instrument air filtering. In three-piece configurations, it adds lubrication to the air, ensuring efficient operation.
Pneumatic solenoid valve: The pneumatic solenoid valve, also known as a directional control valve, is a vital component for regulating the opening and closing of pneumatic valves. It functions by magnetizing and demagnetizing, which directs the gas flow based on voltage signals. Commonly employed to manage gas source and circuit flow, these valves offer precise control over valve operations through voltage signals.
Limit switch: The valve limit switch, also called a travel switch, is a critical field instrument in automatic control systems. It detects the valve’s status and outputs signals for open or closed positions. This switch is essential for confirming and executing subsequent programs by programmers. Additionally, it serves as a vital component for valve interlock protection and remote alarm indication within the system. It effectively indicates and provides feedback on mechanical equipment’s movement limit position.
Valve positioner: The valve positioner is a crucial component of pneumatic control valves, enabling precise control over valve positioning. It utilizes the valve stem displacement signal as input feedback and the controller output signal as the control signal. By comparing these signals, any deviation triggers adjustments to the actuator output signal, ensuring a direct correspondence between valve stem displacement and controller output.
Manual device: The manual device is an essential component that complements the pneumatic actuator assembly. It serves to facilitate manual or pneumatic operation for butterfly valves and ball valves with a 90° opening. This mechanism is crucial for ensuring versatility and flexibility in valve operation, allowing for both manual and automated control as needed.
