Subsea Through Conduit Slab Gate Valve
Highlights
- Robust design
- High sealing capability
- Suitable for high pressure, high temperature
ATV manufactures a full range of Through Conduit Slab Gate Valves for Offshore & Subsea applications in the Oil & Gas exploration and production, suitable for water depths up to 3000 m (10000 ft).
Through Conduit Slab Gate Valves provide superior bubble tight sealing capabilities in gas service and unmatched robustness in harsh services with high pressure, high temperatures (up to 204°C - 400 °F) and solid particles. In addition, Through Conduit Slab Gate Valves are the preferred choice for HIPPS applications, in consideration of the pressure assisted closing feature.
ATV supplies Through Conduit Slab Gate Valves in a wide range of materials and configurations to meet any specific need of the application and customer’s requirements. Many optional features are available for seat and stem seals, CRA welding, hardfacings and end connections.
Materials are sourced from qualified suppliers on the base of specifications that reflect the industry standards (ASTM, NORSOK, BS, DIN or others), but do also incorporate additional requisitions resulting from long experience.
