Marine Control Valves

For the shipbuilding industry, Korean Shipbuilders has a great role to satisfy industrial demand through many types of ships such as LNGC, Container Carriers, Bulk Carrier, Crude Oil Tank, Chemical Tank, Etc. During those big period of abundant shipbuilding, Korean valve manufacturers also has support the development of shipbuilding industry through their enough experience and technology. For ship’s operation lots kind of control valves are essential and those valves are mainly pressure control valve, temperature control valve, flow control valve, etc at many important place with fluids of oil, water, steam and air in ships.
