At Virago Valves, we offer premium gate valves, globe valves, and check valves designed according to the most widely recognized industrial standards: API, BS (British Standard), and ISO. While API is the industry standard, BS and ISO references remain widely used.

We supply cast-body valves, engineered for heavy-duty industrial applications, including oil & gas, (petro)chemical processing, power generation, and pipeline systems.

Gate Valves (API 600, API 603 & API 6D)

• API 600 (BS 1414, ISO 10434) – Carbon steel gate valves with flanged or welded ends and bolted bonnet.
• API 603 – Corrosion-resistant gate valves with flanged or welded ends and bolted bonnet.
• API 6D – Pipeline gate valves with flanged or welded ends, suitable for high-pressure applications.

Globe Valves (API 623)

• API 623 (BS 1873, ISO 15761) – Carbon steel globe valves with flanged or welded ends and bolted bonnet.
  • API lacked its own standard for globe valves for a long time and therefore adopted BS 1873 as a reference.

Check Valves (API 594)

• API 594 (BS 1868, ISO 16767) – Check valves available with flanged ends, wafer type, welded ends, or tapped connections.

Pressure-Sealed Bonnet
Although pressure-sealed bonnets are no longer part of the API standard, they are still covered under MSS SP-144.

Fast delivery for standard and non-standard configurations
We supply valves in standard materials such as WCB, LCB, and CF8M, often with short lead times. If you require non-standard designs, special materials, or small-batch production, availability can be challenging, but we are committed to finding the best solution for your needs.
