Discription

Product Overview

 

The Wafer Centerline PTFE Lined Butterfly Valve features advanced lining technology, with a thick layer of high-grade PTFE (Teflon) applied to all wetted parts, including the valve body, disc, and stem. This ensures exceptional corrosion resistance, making it the ideal solution for handling highly aggressive media such as acids, alkalis, salts, strong oxidants, reducing agents, and organic solvents at any concentration.

It is widely used in demanding industries such as chemical processing, petroleum, pharmaceuticals, food and beverage, steel manufacturing, smelting, and papermaking for reliable flow shut-off and regulation.

Key Features 

 

  • Innovative & Compact Design: Engineered for a lightweight profile with a unique structure that allows for rapid opening and closing.

  • Low Operating Torque: Designed for ease of use, the valve requires minimal force to operate, ensuring smooth and flexible handling.

  • Versatile Installation: Can be installed in any position within the piping system, offering maximum convenience for maintenance and repairs.

  • Superior Bidirectional Sealing: Features a replaceable sealing component that achieves reliable bidirectional zero-leakage performance.

  • Durable Material Construction: The sealing materials are highly resistant to aging and corrosion, ensuring an extended service life even in harsh industrial environments.
