Product Detail

The A105N Forged Steel Trunnion Ball Valve is a high-performance flow control solution engineered for mid-to-high pressure pipeline systems. Constructed from ASTM A105N (Normalized) forged carbon steel, this valve offers superior mechanical strength and improved impact toughness compared to standard casting. The trunnion-mounted design ensures that the ball is fixed by upper and lower bearings, transferring fluid pressure load to the valve body. This significantly reduces operating torque and prevents seat wear, making it an ideal choice for Class 150 to Class 2500 applications in oil, gas, and petrochemical industries.

Design Description

Forged Body Integrity (A105N): The forged construction eliminates internal porosity and defects, while the Normalization (N) heat treatment ensures consistent grain structure and better toughness in low-temperature or high-vibration environments.
Low Torque Trunnion Design: By supporting the ball on bearings, the friction is minimized, allowing for smooth operation even at maximum differential pressure.
Double Block and Bleed (DBB): Fully compliant with API 6D, providing independent upstream and downstream sealing and safe cavity venting for maintenance.
Emergency Sealant Injection: Equipped with secondary sealant injection fittings for both stem and seats to handle emergency leak containment.
Fire-Safe & Anti-Static Design: Certified to API 607 / API 6FA, ensuring structural integrity and sealing safety during fire emergencies.
