Shield supplies class‑approved marine valves for ships and offshore platforms. Our valves meet stringent requirements for seawater corrosion resistance, compact design, and reliability in ballast, cooling, firefighting, fuel, and cargo systems.
ABS / DNV / LR / BV ISO 17579:2025 Seawater Corrosion Resistant JIS Standard Marine Valves
Constant exposure to saltwater demands superior materials: bronze, naval brass, stainless steel 316/316L, and specially coated alloys. Our valves are engineered to withstand marine atmosphere and seawater.
Valves provide bubble‑tight shut‑off to prevent flooding, contamination, or system failure. Designed to meet ISO 17579:2025 and major Classification Societies rules (ABS, DNV, LR, BV, CCS).
Reliable operation under constant vibration, high pressure, temperature fluctuations, and hydraulic shock. Compact designs save valuable space on board.
A modern vessel utilizes a diverse array of valves, each tailored for a specific function and service condition.
Butterfly Valves – Highly versatile, compact, for seawater cooling, ballast, firefighting, and ventilation systems. Fire‑safe designs for engine rooms.
Ball Valves – Excellent sealing and quick quarter‑turn operation. Ideal for fuel oil, lube oil, and critical hydrocarbon services.
Gate Valves – Primary block valves in pipelines where straight‑line flow with minimal restriction is needed.
Globe & Check Valves – Globe for precise flow regulation; check (non‑return) to prevent backflow, protecting pumps and equipment.
Specialty Valves – Quick‑closing valves (remote fuel shut‑off), cryogenic valves for LNG carriers, and pressure relief valves for system protection.
Modern shipbuilding increasingly favors butterfly and ball valves for their compact design, reliable sealing, and quick operation, gradually replacing traditional gate and globe valves in many applications – saving space, reducing weight, and improving responsiveness.
Key Standard: ISO 17579:2025 – new standard specifying design and testing requirements for pneumatic quick‑closing valves used in ship fuel and lubricating oil systems.
