Pneumatic Plastic PVC Butterfly Valves With Fluorine Lined
The standard ISO square size allows for the direct mounting of actuators, ensuring compatibility and ease of installation. The disc and seat feature a trapezoidal elastic lining, which ensures a hermetic seal, enhancing the valve’s performance and reliability.
Furthermore, the bushing serves to completely isolate the valve body from the process flow, preventing any contamination or interference. Acting as flange gaskets on both sides of the valve, the bushings contribute to the overall sealing integrity of the system.
To prevent liner slippage and compression, the body cavity is equipped with special channels, ensuring the stability and longevity of the valve’s components. Additionally, EPDM, NBR, and PTFE seal O-rings are employed to provide effective shaft sealing, further enhancing the valve’s sealing capabilities across various operating conditions.

Air source processor: Combines filtering, pressure reduction, and lubrication functions, ensuring stable outlet pressure. Available in two-piece assemblies for filtering compressed instrument air and three-piece configurations for added lubrication.
Pneumatic solenoid valve: Regulates the opening and closing of pneumatic valves by magnetizing and demagnetizing to direct gas flow based on voltage signals. Offers precise control over valve operations, commonly used for managing gas source and circuit flow.
Limit switch: Detects valve status and outputs signals for open or closed positions. Critical in automatic control systems, confirming and executing subsequent programs, providing valve interlock protection, and indicating remote alarms within the system.
Valve positioner: Crucial for precise control over valve positioning in pneumatic control valves, comparing valve stem displacement and controller output signals, adjusting the actuator output signal accordingly.
Manual device: Complements pneumatic actuator assemblies, facilitating manual or pneumatic operation for butterfly and ball valves with a 90° opening. Ensures versatility and flexibility in valve operation, allowing for manual and automated control as needed.
