Naval and Marine Valves

Marine Valves
Global Trade Link specialises in the design, manufacture and supply of high-integrity valves and fittings to the UK Ministry of Defence (Navy) and foreign navies worldwide. The GTL product portfolio includes pressure reducing, pressure sustaining, relief/safety relief valves and submarine in line valves.
Naval Valves and Fittings
Our range of naval valves and fittings include: Pressure Reducing Valves Pressure reducing valves for naval applications are manufactured to NES375 and NES 360, in sizes from 15mm to 200mm with a maximum working pressures up to 275 bar and more. Comprehensive stock is carried to service the needs of fleets. We also specialise in the manufacture and design of special valves to customer’s specifications, having our own pattern making and foundry facility enables us to turn ideas into reality quickly and under our control. The company specialises in providing solutions where the original equipment is no longer available to the Ministry of Defence (Navy) or fit for purpose. During the past three years the majority of pressure reducing valves fitted to new naval shipping have been supplied by GTL. This means that the usual warming up period can be significantly reduced.
Relief and Safety Relief Valves
Relief and safety relief valves complement our reducing valve range, manufactured to NES 375 and NES 360. They are used to protect equipment and pipelines downstream from over pressurisation and are available in a range of sizes from 15mm to 200mm with a maximum working pressure of up to 400 Bar. Safety valves differ from conventional relief valves in the fact that they are accredited to a national body, either the American Petroleum Institute (API), American Society of Mechanical Engineers (ASME) or to other European Standards such as BS 6759 and TUV. The safety valves manufactured by GTL are to the API specification, and expanded to ASME, BS 6759 and TUV. Typical applications for the above types of valves include:
Auxiliary steam systems
Desalination units
Diesel exhaust
Diesel seawater cooling
Diesel lube oil systems
Main feed water systems
Hot and cold domestic systems
Trim bilge and ballast systems
Chilled water systems
Fire fighting systems
Submarine Inline Hull Valves
Inline and hull penetration valves

All
products are designed and/or manufactured to suit shipbuilders' specific
requirements for first level applications. Multiple Valve Chests, Manifolds and
Bulkhead Fittings SDSL/SDNR/Gate valves all designed and/or manufactured to
suit specific requirements. The company specialises in producing valves in
Nickel Aluminium Bronze and Cupro Nickel to all relevant national and international
naval engineering specifications. Full radiographic, dye-penetrant and
ultrasonic wall thickness examination is carried out on pressure-retaining
components. All valves supplied by GTL are backed by the company's through-life
support services.
