Manufacturer: Ledeen
HS Series

Experienced Cameron engineers designed an integrated adjustable travel stop subassembly for precise valve positioning (patent pending).

  • Independently adjustable open and close travel stops
  • Precise valve setting to fully open for optimized flow and to fully closed for positive shut-off position
  • External access to travel stop adjustment
  • Setting retention with an integrated locking mechanism

The LEDEEN compact hydraulic actuator is a quarter-turn actuator ideal for space-constrained installations, including

  • floating production, storage, and offloading (FPSO) vessels, platforms, and offloading buoys
  • drilling diverters, carbon dioxide (CO2), and liquid mainlines
  • mining operations.
