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
- ROV override
- Microswitch for open-close indication
- Position transmitter for 0% to 100% travel indication
- 100% radiographically and liquid-penetrant-inspected welds
