Y Strainers - Pumps, Valves, Piping and Fittings
A Y-strainer is an inline mechanical filter installed in marine piping to remove debris from seawater, ballast water, cooling water, fuel, lubricating oil, and other fluids. Its Y-shaped body contains a removable perforated or mesh screen that protects pumps, valves, meters, and heat exchangers.
ProShipWorks provides end-to-end support to source and supply Y Strainers 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 requirements may include ASME B16.34 for pressure-containing valve bodies, ASME B16.5 or EN 1092-1 for flanged connections, and relevant manufacturer pressure-testing procedures. The exact standard depends on material, size, pressure class, and service. |
|---|---|
| Class Approval | Y-strainers are not universally class-approved as standalone items. Marine installations may require acceptance or type approval by DNV, ABS, Lloyd's Register, Bureau Veritas, or ClassNK, depending on vessel rules, system service, and project specifications. |
Installation, Maintenance & Safety Information
| Installation Notes | Install with the flow arrow in the direction of fluid flow and the strainer pocket oriented downward or as specified by the manufacturer. Provide isolation valves and sufficient clearance for screen removal. Support connected piping and verify pressure, temperature, material, and gasket compatibility. |
|---|---|
| Maintenance Tips | Monitor differential pressure and clean the screen when pressure loss increases or flow decreases. Isolate, depressurize, drain, and cool the line before opening the cover. Inspect the screen, gasket, body, and drain plug for corrosion, erosion, blockage, or damage. |
| Safety Notes | Never remove the cover while the line is pressurized or hot. Use appropriate personal protective equipment for the fluid being handled. Confirm isolation and zero pressure before maintenance, and use screens rated for the system pressure and temperature. |
