Functional types

Note

 

Attention is drawn to Note (2) following the title of subclass G 05 D and also the subdivisions of that subclass, according to which pressure regulators and flow regulators, e.g. flow regulating valves with pressure compensator, even with the whole regulating system contained in a valve, operating with or without auxiliary power, are covered by groups G 05 D 16/00 or G 05 D 7/00, respectively. However, details of the valve parts, per se, are classified in the appropriate groups of this subclass. [2]
