  1. Características principales
  1. Soft Seating
  • PTFE or reinforced PTFE seats offer excellent self‑lubrication and tight shut‑off (zero leakage).
  • Low friction torque, smooth operation, and extended service life.
  • Blow‑out Proof Stem
    • Stem is inserted from inside the body, preventing ejection under pressure, ensuring safety even in abnormal pressure conditions.
  • Antistatic Device (Optional)
    • Grounding springs provide electrical continuity between ball, stem, and body to prevent static charge buildup in hazardous environments.
  • Bidirectional Sealing
    • Floating ball design allows equal sealing in both directions; no orientation limitation.
  • Fire Safe Design (Optional)
    • Conforms to API 607 / ISO 10497. In case of soft seat burnout, secondary metal‑to‑metal sealing maintains basic integrity.
