Oviko Group has been manufacturing API 6A wellhead ball valves since 2018 and has obtained API 6A certification. The full range of wellhead equipment and Christmas tree ball valves produced by Oviko comply with the latest edition of relevant API specifications.

The BTS series API 6A wellhead ball valves developed and manufactured by Oviko Group are suitable for harsh conditions such as wellheads, Christmas tree equipment, and the shut-off of various fluid and gas media (e.g., oil-sand mixtures and extreme sourgas environments).

Oviko API 6A wellhead ball valves adopt a 2-piece or 3-piece side-entry body structure with bolted body connections. Soft or metalseals can be configured on the sealing faces. Pressure-containing and core components are made of forged materials to improve the strength, rigidity and safety of high-pressure valves, ensuring high reliability in various temperature, pressure and media conditions, and meeting customers' continuously increasing high-level quality requirements.
