KOSEN is a primary manufacturer of valves for offshore topside systems including Platforms, FPSO, and FLNG. Because of the severe operational conditions (corrosive environment, high pressure, salty air & water, deep water etc.), valves being used for offshore topside systems should be specially designed and manufactured with anti-corrosive material, sealing and paint. KOSEN provides application specific valves for offshore industries which include ball, butterfly, gate, globe, and check valves. With high stability, reliability and safety performance.
