Summary
Top-entry, springless trunnion-mounted ball valve featuring wedge-seat geometry and self-levelling seats for leak-tight shutoff and in-line maintenance capability; designed for severe-service, high-pressure and cryogenic/high-temperature applications.

Key features

• Wedge-seat design ensuring leak-tight shutoff and self-adjusting seats for consistent sealing performance.
• Top-entry construction enabling in-line maintenance to minimise downtime.
• Trunnion-mounted ball for robust support under high differential pressures.
• Bi-directional fire-safe sealing and anti-static design.
• Anti-blowout stem for enhanced operational safety.
• Suitable for manual and actuated operation.
• Wide temperature capability from -254°C to +320°C depending on materials and configuration.

Applications

• Oil & gas production and transport
• Petrochemical plants
• LNG facilities
• Purified terephthalic acid (PTA) plants
• Hydrogen service and H2-ready installations
• Steam, hydrocarbons and multi-phase fluids

Construction & options

• Trunnion-mounted ball construction for stable operation in high-pressure and severe-service conditions.
• Self-levelling seats with wedge-seat geometry for tight shutoff and long-term sealing performance.
• Available materials: carbon steel, stainless steels, low alloy steels, nickel alloys, duplex & super duplex, titanium; other alloys on request.
• End connections: ANSI, NORSOK, welded ends and other flange/connection options on request.
• Configurations optimised for manual or automated (actuated) operation.

Performance & safety

• Maximum working pressure up to 250 barg depending on size and material selection.
• Bi-directional fire-safe sealing and anti-static features for critical-service safety.
• Anti-blowout stem and design elements to minimise leakage and preserve integrity under severe conditions.

Standards & certifications

• Design codes: API 6D, ASME B16.34, ASME VIII Div.1, ASME VIII Div.2.
• Certifications: PED, NACE, SIL3, ABS, DNV, LR, BV, CU-TR, API 607, API 6FA, ISO 15848, ISO 10497.
