Hydraulic Directional Control Valve (HCV)

Hydraulic Directional Control Valves (HCVs) are used to control various critical functions of a subsea X-mas Tree (XMT) and other well access tooling.


60,000 Subsea HCVs Supplied Worldwide

We put our first HCV on the seabed in 1993. Today, we have supplied nearly 60,000 subsea HCVs. They are key components in 40% of the world’s subsea wells.


Using HCVs in Harsh Subsea Environments

Oceaneering has developed a range of HCVs suitable for use in harsh subsea environments with pressures up to 1,380 bar (20,000 psi) and depths of 4,000 m (13,120 ft).

Our valves are based on the “metal to metal seal” principle, with a design that improves performance, reliability and robustness.

Our HCVs utilize electro-hydraulic pilot, or direct hydraulics to operate the main stage.


Key Features of HCV

  • High pressure
  • Extremely robust and contamination tolerant design
  • Built clean, using superior materials
