ANSI face to face dimensions

Buy a copy of ASME B16.10:
Here is a good source for digital standards or you can buy it directly from ASME

You may need more standards and dimensional criteria than just ASME B16.10.
Several control valve dimensional standards exist. ISA-75.08.03 covers globe valves with dimensions for socket weld and screwed valves. ISA 75.08.07 covers separable flanged globe valves. Other standards cover other connections and valve patterns etc.
Some supplier catalogs provide the face to face dimensions and advise which standard. Many valves are offered with several dimensional selections. So first determine what type valves and what codes and standards apply for the project. For example I recently requisitioned ball and butterfly valves and specified the dimensions to comply with the ASME B16.10 long pattern dimension for gate valves. Perhaps some and not all manufacturers can comply with such requests.
