3、rldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented o
4、n that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards ado
5、pted by the technical committees are circulated to the member bodies for voting. Publication as an Inter- national Standard requires approval by at least 75% of the member bodies casting a vote. International Standard IS0 10372 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Sub

This International Standard specifies the dimensions of surfaces on
11、 which servovalves are mounted in order to ensure interchangeability. It applies primarily to electrohydraulic flow-control servovalves which represent current industrial practice. It is applicable to four-port servovalves and also to five-port types, i.e. those in which the pilot stage is supplied
12、with hydraulic fluid separately from the remaining stages. In addition, this International Standard may be used for pressure-control servovalves. If the valve is used in a three-port ap- plication, either service port (A and B) may be omitted. Because there is no clear distinction between servovalve
13、s and certain proportional control valves in performance and/or application, the existence of this mounting surface for servovalves does not ex- clude the use of a mounting surface as specified in IS0 4401.
