Hydraulic Subsea Actuators

The Cameron portfolio of LEDEEN* actuators includes hydraulic subsea actuators designed for shallow-water and deepwater applications. Both actuator types can operate with a supply pressure up to 3,000-psi [207-bar] gauge pressure.

Deepwater series For installations beyond 500-ft [152-m] water depth

Shallow-water series (S-GS and S-SY models) For installations to 500-ft [152-m] water depth

Available options

  • Manual override
