Hydraulic Actuators - Pumps, Valves, Piping and Fittings
Hydraulic actuators convert pressurized hydraulic fluid into controlled linear or rotary motion for marine machinery. They are used with pumps, directional valves, piping, hoses and fittings in steering gear, deck equipment, cranes, hatch covers and remotely operated valves.
ProShipWorks provides end-to-end support to source and supply Hydraulic Actuators for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Hydraulic cylinders may be designed to ISO 6020/2 or ISO 6022. Hydraulic system design and safety practices are covered by ISO 4413. Material, testing, pressure ratings and documentation remain manufacturer- and project-specific. |
|---|---|
| Class Approval | Marine installations may require approval or acceptance by DNV, ABS, Lloyd's Register, Bureau Veritas, ClassNK or another vessel class society. Approval is normally equipment-, drawing- and application-specific rather than universal for every actuator. |
Installation, Maintenance & Safety Information
| Installation Notes | Verify actuator force, stroke, speed, mounting geometry, pressure rating, fluid compatibility and allowable side load. Flush and filter the hydraulic system, install correctly rated hoses and fittings, align the actuator, and bleed trapped air before commissioning. |
|---|---|
| Maintenance Tips | Inspect seals, rod surfaces, mounts, hoses and fittings for leakage, corrosion or damage. Check hydraulic oil cleanliness, pressure and temperature, and replace filters and seals according to the maintenance schedule. Record abnormal drift, noise or operating force. |
| Safety Notes | Isolate the hydraulic power source, lock out controls and fully depressurize the circuit before work. Secure suspended or moving loads mechanically. Use components rated above the maximum system pressure and never search for leaks with hands. |
