Features & Benefits

Fully PFA lined butterfly valves engineered for bidirectional bubble-tight shutoff in demanding corrosive, chemical, semiconductor, and ultrapure water applications.

  • A. Fully PFA lined disc and body

    Proprietary compound provides unsurpassed resistance to corrosion, permeation, and microbial contamination for maximum purity and reliability with minimum maintenance.

  • B. Durable, spherically molded PFA liner and matching disc

    Interface forms a tight bidirectional seal.

  • C. Full width 360° seat energizer

    Ensures uniform sealing.

  • D. Live-loaded, stem sealing system

    Self-adjusts to eliminate leak paths and reduce fugitive emissions for long-term, maintenance-free operation. (Standard sealing system meets ISO 15848-1 low fugitive emission requirements.)

  • E. Extended PFA shaft over-molding

    Enhances stem sealing, eliminates leak paths, and shields the stem from corrosive media.

  • F. PFA disc over-molding

    PFA resin is mechanically bonded to the base metal to enable vacuum capability.

  • G. Streamlined disc

    Engineered for maximum flow.

  • H. High-strength, one-piece 17-4 stainless steel disc and stem

    Standard for improved reliability.

  • I. Energized flange seal

    Maintains proper sealing between valve and flange.

  • J. Mechanically retained seat energizer

    Wide elastomer seat energizer rests in a machined body groove to enable end-of-line service at full working pressure.
