Butterfly Valve Actuators - Pumps, Valves, Piping and Fittings
Butterfly valve actuators provide controlled opening, closing, and throttling of butterfly valves in marine piping systems. They may be electric, pneumatic, or hydraulic and are selected according to valve torque, operating environment, control system, and required fail position.
ProShipWorks provides end-to-end support to source and supply Butterfly Valve 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 | Commonly referenced standards include ISO 5211 for valve actuator mounting, EN 15714-2 for electric industrial valve actuators, EN 15714-3 for pneumatic actuators, IEC 60529 for enclosure protection, and IEC 60034 for rotating electrical machines. Product-specific certification must be verified. |
|---|---|
| Class Approval | Marine suitability and type approval may be available from DNV, ABS, Lloyd's Register, Bureau Veritas, and ClassNK, depending on the exact actuator, enclosure, installation location, and vessel notation. Verify the manufacturer's current certificate for the supplied configuration. |
Installation, Maintenance & Safety Information
| Installation Notes | Confirm valve torque, rotation angle, mounting interface, supply voltage or air pressure, fail position, and control signal before installation. Align the actuator with the valve stem, install suitable supports, and set mechanical or electronic travel limits according to the manufacturer's instructions. |
|---|---|
| Maintenance Tips | Inspect mounting bolts, valve stem coupling, cabling, air lines, seals, and position indicators periodically. Exercise seldom-used valves, check for corrosion and water ingress, verify limit switches and torque settings, and lubricate only where specified by the manufacturer. |
| Safety Notes | Isolate and depressurize the piping system before installation or maintenance. Apply electrical lockout and tagout, isolate pneumatic or hydraulic energy, and confirm the valve position before removing the actuator. Do not exceed the rated torque, pressure, temperature, voltage, or hazardous-area classification. |
