PTFE Sleeve Butterfly Valves: The Standard for Chemical Integrity

A PTFE Sleeve Butterfly Valve utilizes a high-grade Polytetrafluoroethylene (Teflon) seat that entirely sleeves the internal bore. This design is exceptionally popular because it combines the lightweight, compact nature of a butterfly valve with the extreme chemical resistance of PTFE. Whether you are managing acids, alkalis, or high-purity solvents, FlowBiz ensures your media remains uncontaminated and your valve body remains protected.

Understanding the Three Geometric Types

FlowBiz manufactures all three primary configurations to suit varying pressure and temperature needs:

  1. Zero Offset: The stem passes through the centerline of the disc and seat. Ideal for low-pressure, resilient-seated applications.
  2. Double Offset (High Performance): The stem is displaced from the center, creating a cam-like action that reduces seat wear.
  3. Triple Offset: The ultimate "Zero Leak" metal-seated valve for high-pressure, fire-safe environments in the oil and gas sector.
