John Valve is a leading marine valve manufacturer in Taiwan. We are the first Lloyds Register approval manufacture in the Asia region. We have been supplying valves to the 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 from damage and fully functional.
