주요 특징

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.
