Subsea Needle Valves
Subsea DBB manual operated needle valves
SAMI’s subsea DBB manual operated needle valves are designed for upstream subsea application,
where precision and high quality performances are required. They are commonly used with natural
gas or more viscous fluids, like hydraulic oil at high pressures.
SAMI’s subsea DBB valves include double seal O-Rings to prevent any seepage towards the internal
parts of the valve. Thanks to its improved design, our subsea valve presents a low torque value, which
remains unaltered in time.
Our subsea DBB valves are also available in other configurations and in a variety of connections
according to our customers’ needs.
Our DBB valves are designed and manufactured in compliance with the standards API6D-SS, ASME
VIII, EEMUA 182 and ISO 13628-8.
