Description

NSW API 6D Ball Valve – Class 150–2500, WCB/F316/F51, Trunnion or Floating Design

The NSW API 6D Ball Valve is a heavy-duty isolation valve designed for high-integrity pipeline service in oil & gas, petrochemical, and power industries. Manufactured in accordance with API 6D and ASME B16.34, it is available in floating or trunnion-mounted configurations with full or reduced bore. Sizes range from 2" to 60" and pressure ratings from Class 150 to Class 2500, making it ideal for low to high-pressure systems.

The valve is offered in side-entry, top-entry, or fully welded body designs. Standard features include anti-blowout stem, anti-static device, fire-safe construction per API 6FA/API 607, and optional emergency seat/stem sealant injection. With options for double block & bleed (DBB) or double isolation & bleed (DIB), it is suitable for critical shutoff and control applications.

The ball valve’s internal cavity offers low turbulence and minimal pressure drop. Materials include cast or forged carbon steel, stainless steel, duplex, super duplex, and high-nickel alloys, allowing compatibility with water, gas, oil, acid, steam, and aggressive media.
