ACTUATOR TYPE: Subsea

Helical Spline® Actuators


MAIN FEATURES:

  • Compact ergonomic and tailor-made design for manifold application
  • Piston with linear movement only, instead of linear and rotary
  • Cylinder chamber separated from helical spline chamber for excellent hydraulic oil cleanliness and actuator long life
  • Linear output torque guarantees proper valve stroke even at overlap angle
  • High Helical Spline® mechanism contact surface, low specific stress values preventing wear and deformation
  • Suitable and reliable for high number of strokes and fast operations
  • Factory set end stops for perfect valve stroke and alignment
  • High strength materials for internal parts and seawater resistant materials for all exposed parts
  • Redundant dynamic sealing on piston and external moving parts
  • Easily visible tactile position indicator
  • With optional ROV interface for ROV/manual operation
