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.

Advantages

  • All models available as double acting or spring return
  • High torque outputs
    • 57,360 lbf.in [6,480 N.m] for S-GS model
    • 5,700,000 in.lbf [644,000 N.m] for S-SY model
    • 3,600,000 in.lbf [400,000 N.m] for deepwater model
  • Open and close travel stops provide ±3° minimum
  • Scotch yoke mechanism generates powerful opening and closing torque outputs
