I'm not aware of a specific prohibition, and NFPA 13 2010 "6.7.4.3.1* Systems that have more than one control valve that must be closed to work on a system or space shall have a sign referring to existence and location of other valves." would suggest to me it's OK as long as that requirement is met?
