PTFE Lined Butterfly Valve

Two pieces of body  butterfly valve adopt a concentric disc and seat configuration with a complete PTFE sealed structure. The body undergoes a complete package PTFE painting process. The painting thickness can reach up to 3-4mm, effectively preventing the direct interaction between the body and the medium and the corrosion of the body by the medium.

Description



 Product Fearues  

  • Absolutely Tight Sealing: Ensures leak-proof performance with flow in either direction, providing superior sealing capabilities.

  • Low Operating Torque: The precisely machined valve body and disc contribute to reduced operating torque, making the valve easier to operate and more energy-efficient.

  • Long Service Life & Reliability: The PTFE lining prevents corrosion, extending the valve’s lifespan and enhancing overall reliability, even in harsh or corrosive environments.

  • Disassembly & Recycling: The valve can be disassembled for maintenance or repair, and the materials are recyclable, supporting sustainable practices in industrial settings.
