Ships and marine technology. Metal valves for use in flanged pipe. Face-to-face and centre-to-face dimensions Ingestion-build-67170 The procedures to be used1 Scope This International Standard specifies the basic series of face to face or centre to face dimensions for two way metal valves used in flanged pipe systems for ship and marine services. Each series of face to face or centre to face dimensions can be used as required with flanges of mating dimensions conforming to ISO 7005 1, ISO 7005 2, and ISO 7005 3 or other national standards. The range of pressure ratings, in K values, is 5 10 16 20 30 40
