Marine Shipbuilding

John Valve is a leading marine valve manufacturer in Taiwan. We are the first Lloyds Register approval manufacture in the Asia region. We have supplied valves in maritime industries for over 30 years.

For Marine & Shipbuilding applications, the equipment must be suitable for use in seawater environments. In addition, excellent corrosion resistance is essential to keep valve surfaces free of damage and fully functional. John Valve manufactures various Ball Valves capable of withstanding these weather challenging conditions. Our valves are built for long service life and are reliable even in critical weather conditions.

John Valves holds major classification society certificates approvals, such as Det Norske Veritas (DNV), Lloyds Register, Bureau Veritas. And while other classification societies like CCS, NK, KR, RINA, ABS is upon shipowners’ request and welcome to cooperate
