RGS Ledeen Subsea Gears
Scotch yoke design for shallow-water and deepwater applications
Purpose-engineered for reliable valve actuation in the most challenging subsea environments.
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.
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
- Buna rubber piston seal configurations specifically designed for hydraulic applications
- Composite guide band on piston provides low-friction guidance and support
- Epoxy-coated prestressed springs provide consistent performance with corrosion protection
- Pressure compensator balances oil-filled cavity with ambient pressure
