Dedicated Subsea & Marine Valve Hydraulic Actuation Solutions - D Series Hydraulic Actuator

Dedicated Subsea & Marine Valve Hydraulic Actuation Solutions

From Offshore Deep-Sea 330m to Marine Industry Excellence

Reliable performance from shipboard ballast tanks to 330m subsea manifolds. Marine-grade engineering, operational from -20°C to 80°C.

D Series heavy-duty hydraulic actuator designed for 3.3MPa (330m) subsea applications with IM4 protection.

D Series: 330m Deep-Water Hydraulic Actuator

Beyond Ballast Tanks: Engineering for the Subsea Frontier.

Built for the 330m Pressure Envelope

While standard marine actuators stop at 50m, the D Series is engineered for the abyss. As a premier subsea hydraulic actuator, it features a reinforced heavy-duty housing designed to maintain seal integrity and mechanical stability under the constant 3.3 MPa (330m) hydrostatic pressure found in deep-sea manifolds. This high-spec submersible hydraulic actuator is the definitive choice for long-term seabed installations.
