3. Key Technical Parameters

4. Material of Construction (Typical)

Materials must comply with NACE MR0175 requirements based on PSL and sour service conditions.

5. Features & Design Advantages

1. Trunnion-Mounted Ball / Floating Seat Design: The ball is supported by fixed upper and lower trunnions (shafts), minimizing deformation under high pressure. Seats are spring-loaded and pressure-assisted to ensure bubble-tight bidirectional sealing at both low and high pressures.
2. Anti-blowout Stem: The stem is internally retained by the bonnet shoulder, preventing stem ejection under abnormal high pressure.
3. Fire-safe Structure: Designed to API 6FA. In case of fire, if soft seats are destroyed, the ball contacts the metal seat backup to form a secondary metal-to-metal seal. A graphite secondary sealing element in the stem prevents external leakage.
4. Anti-static Device: Springs and conductive balls are installed between the stem, ball, and body to ensure electrical continuity even with non-metallic seals, preventing static charge buildup.
5. Emergency Sealant Injection: Optional sealant injection fittings are available for seats and stem. In case of accidental seal failure, special sealant can be injected to temporarily restore sealing.
6. Double Block and Bleed (DBB): In the fully closed position, the valve isolates both upstream and downstream pressure simultaneously. The body cavity pressure can be relieved via a bleed valve to verify seal integrity.
7. In-line Maintenance (Top Entry): Top entry design allows for replacement of internal components like the ball and seats without removing the valve body from the pipeline.

6. Options & Accessories

• Extended Bonnet: For cryogenic/low-temperature applications.
• Drain / Vent Connections: Threaded connections with plug indicators.
• Position Indicator: Visual open/closed indication.
• Locking Device: To prevent unauthorized operation.
• Actuator Mounting Pad: Standardized to ISO 5211.
