Subsea Compact Insert-Retrievable Choke Valve

Brand: Cameron

Our latest innovation is the revolutionary subsea insert-retrievable compact choke with a dog-in-window connector that offers substantial advantages.

This type of subsea insert-retrievable choke is 35% smaller and 45% lighter than a traditional clamp running tool (CLRT) subsea choke.

It also provides total vertical access for insert retrieval.

Total vertical access is achieved via push/pull rods that engage/disengage dogs for insert installation and retrieval, with the option of hydraulic override for disconnect.

And, because it requires no horizontal access, the choke can be more centrally placed, potentially reducing the size and weight of the production tree and manifold significantly.

In addition, installation is simple enough for smaller, more readily accessible vessels to handle.

The compact choke features our field-proven hydraulic stepping linear choke actuator (SLCA), along with an increased trim cavity and annular area for reduced flow velocity and a more uniform fluid presentation to trim.

Several cage-style trims are available, including plug and cage for reverse and forward flow and maximum Cv, and water injection multistage, the choice for long-term operation in cavitation-sensitive conditions and reverse flow applications.
