Subsea LEDEEN Actuators

Shallow- and deepwater series

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 and shallow-water LEDEEN actuators.
