Using the same technology from our Single Isolation Ball Valves, we can supply units with double block or double block & bleed functionality. All units can be fitted to a single valve body, providing a compact, lower weight solution. Available in sizes from 3/8” up to 16”, and pressures up to 15,000psi
Our subsea valves are suitable in water depths to 3.000 m (10.000 ft) and maintain an average service life of 25 years while offering the utmost level of reliability and safety under high-pressure conditions-even in harsh service with the presence of sand or solid particles.
Valves are available in a wide range of materials and configurations to meet both customer requirements and specific application needs.
