1 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. Each basic series of face-to-face or centre-to-face dimensions may be used as required with flanges of mating dimensions conforming to ISO 2084 or ISO 2229.
2 The range of pressure ratings, in PN values, is 1-1,6-2,5-4-6-10-16-25 and 40. and classes 125 - 150 - 250 - 300 and 600.
3 The range of nomina\ sizes, in DN values, is
10-15-20-25-32-40-50-65-80-100-125 - 150 - 200 - 250 - 300 - 350 - 400 - 450 -500 - (550) - 600 - (650) -700-750-800-900-1 000 - 1 200 - 1 400 - 1 600 - 1 800 and 2 000.
