BSI BS ISO 17602:2014

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 and those specified in ISO 5752.

The range of nominal sizes, in “DN? or “A? values, is 15 - 20 - 25 - 32 - 40 - 50 - 65 - 80 - 100 - 125 - 150 - 200 - 250 - 300 - 350 - 400 - 450 - 500 - 550 - 600 - 650 - 700 - 750 - 800 - 900 - 1 000 - 1 200.

NOTE For information, pressure ratings at room temperature (cold ratings up to 120 °C) of K-series flanges are approximately as follows.

Pressure class 5K 10K 16K 20K 30K 40K
Pressure rating (RT) 0,7 MPa 1,4 MPa 2,2 MPa 3,4 MPa 5,1 MPa 6,8 MPa

Pressure rating can differ by valve materials, sizes, and types. Reference shall be made to relevant product standards. For details of pressure temperature ratings of K-series flanges, refer to JIS Standards in the bibliography of this International Standard. JIS F7300 specifies a comprehensive guide for selection of valves listed in Tables 1 to 5.
