Marine Valves & Cocks (IMPA 75)
IMPA section 75 covers the valves and cocks that control every fluid system on a ship, from seawater cooling and bilge lines to fuel and cargo piping. The category spans JIS, DIN and ANSI standards, and the highest-volume sub-types are butterfly, gate and globe valves along with their wear components — seats, spindles and actuator springs. Buyers source these by IMPA code, valve standard and nominal bore, and the same six-digit code resolves to a specific size and material so a purchaser can order without ambiguity. Because valves sit in safety and pollution-relevant systems, class approval and material traceability apply to most piping service. This hub organises the standards, the common sub-components and the curated valve subtypes that make up routine piping maintenance across the fleet.
Valve standards and sizing
JIS, DIN and ANSI valves differ in flange drilling and pressure class, so the standard and nominal bore must match the existing line. The IMPA code encodes the type, size and material for unambiguous ordering.
Regulatory overview
Valves in fire, bilge and fuel systems fall under SOLAS and MARPOL-relevant piping rules and generally require class material approval and EN 10204 material traceability. Standard compliance (JIS, DIN, ANSI) must match the existing flange and pressure rating.
