SUBSEA LINEAR HYDRAULIC ACTUATORS
ACTUATOR DESCRIPTION
Subsea linear hydraulic actuators for slab gate valves are designed for deep water application with hydraulic operating pressure of 3000psi or 5000psi as per Customer requirements.
Actuators are design in accordance with API17D with the addition of customer requirements when present.
All models are equipped with mechanical override intervention mechanism and can be provided with remote indicator (continuous or limit switches). The mechanical override can be designed not compressing the spring and bypassing the hydraulic piston
BASIC CHARACTERISTICS
- API17D design as requested
- All models available double acting (DA) and spring return (FSC or FSO)
- Hydraulic system assembled in clean environment (ISO8 clean room) and flushed to SAE AS4059 6B-F
- Visual and remote (continuous or limit switches) position indicator
- Balanced pressure cavities with local open or close compensation systems or common sea chest

SUBSEA QUARTER TURN ACTUATOR
ACTUATOR DESCRIPTION
Subsea quarter turn hydraulic actuators are designed for deep water application with hydraulic operating pressure of 3000psi or 5000psi as per Customer requirements. Actuators are design in accordance with API17D with the addition of customer requirements when present.
The core mechanism of the actuator can be Rack & Pinion or Helical Spline. All models can be equipped with mechanical override intervention mechanism and all models can be diver or ROV retrievable.
Helical Spline mechanical override can be designed not compressing the spring.
BASIC CHARACTERISTICS
