Hydraulic Directional Control Valves

Delivering Reliable Solutions

Our hydraulic directional control valves (HCVs) are key components in 40 percent of the world’s subsea wells. HCVs control critical subsea X-mas tree (XMT) and well access tooling functions within subsea manifolds and control systems.

Over the past 25 years, we have supplied more than 60,000 subsea HCVs.

Operating in harsh subsea environments

Our HCVs are suitable for use in harsh subsea environments, and are designed to meet pressure requirements up to 20,000 psi (1,380 bar) and working depths of 13,120 ft (4,000 m).
  • High pressure ratings, extremely low leakage
  • Industry-leading robustness and contamination-tolerant design
  • Use electro-hydraulic pilot or direct hydraulics to operate the main stage
  • Solenoid or direct hydraulic operated
  • Certified for use in safety integrity level (SIL) systems
