Metal valves for use in flanged pipe systems. Face-to-face and centre-to-face dimensions
This document specifies the basic series of face-to-face (FTF) and centre-to-face (CTF) dimensions for two-way metal valves of the gate, globe, diaphragm, ball, plug, butterfly design types used as isolating and check valves in flanged pipe systems. Each basic series of face-to-face and centre-to-face dimensions can be used as required with flanges of mating dimensions conforming to the equivalent EN or ASME flange series.
This document covers valves with the following PN, Class, DN and NPS values:
PNÂ 2,5; PNÂ 6; PNÂ 10; PNÂ 16; PNÂ 25; PNÂ 40; PNÂ 63; PNÂ 100; PNÂ 160; PNÂ 250; PNÂ 320; PNÂ 400;
Class 125; Class 150; Class 250; Class 300; Class 600; Class 900; Class 1Â 500; Class 2Â 500;
