Flow Control Valves - Pumps, Valves, Piping and Fittings
Flow control valves used in marine pump, piping and fitting systems regulate, isolate or direct liquid and gas flow. Common types include butterfly, globe, ball, gate, check and control valves, supplied with manual, pneumatic, hydraulic or electric actuation.
ProShipWorks provides end-to-end support to source and supply Flow Control Valves 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 | Applicable standards may include ISO 5208 for pressure testing, ISO 5752 for face-to-face dimensions, EN 593 for metallic butterfly valves, API 598 for valve inspection and testing, and API 609 for butterfly valves. Exact requirements depend on valve type and service. |
|---|---|
| Class Approval | Marine installations may require type approval or product certification from DNV, ABS, Lloyd's Register, Bureau Veritas, ClassNK, RINA or another recognized classification society. Approval depends on valve design, material, pressure, service and vessel notation. |
Installation, Maintenance & Safety Information
| Installation Notes | Verify valve size, pressure rating, flow direction, material compatibility and flange standard before installation. Clean and align piping, avoid pipe strain, use correct gasket and bolt tightening, and confirm actuator clearance and fail position. |
|---|---|
| Maintenance Tips | Inspect for leakage, corrosion, abnormal operating torque and actuator faults. Exercise manually operated valves periodically, test automated valves and limit switches, lubricate where specified, and replace damaged seats, seals or packing. |
| Safety Notes | Isolate, depressurize, drain and lock out the system before removal or maintenance. Treat fuel, steam, seawater and chemical lines as hazardous according to service conditions. Use rated lifting equipment and never exceed the valve pressure or temperature limits. |
