4. Belangrijkste kenmerken

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.

• Stem is inserted from inside the body, preventing ejection under pressure, ensuring safety even in abnormal pressure conditions.

• Grounding springs provide electrical continuity between ball, stem, and body to prevent static charge buildup in hazardous environments.

• Floating ball design allows equal sealing in both directions; no orientation limitation.

• Conforms to API 607 / ISO 10497. In case of soft seat burnout, secondary metal‑to‑metal sealing maintains basic integrity.

5. Dimensions & Weight (Reference)

Values are typical for EN 1092‑1 PN40 RF flanges. Final dimensions to be confirmed from certified GA drawings.

6. Design & Manufacturing Standards

Testing:

• Shell strength test: 1.5 × rated pressure
• Low‑pressure seat test: 0.6 MPa
• High‑pressure seat test: 1.1 × rated pressure
