12、blankBSISO10372:1992 ii BSI 05-1999 Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body i

13、nterested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison withISO, also take part in the work. ISO collaborates closely with the International Electrotechni

14、cal Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote. In

15、ternational StandardISO10372 was prepared by Technical Committee ISO/TC131, Fluid power systems, Sub-CommitteeSC5, Control products and components.

16、 tolerances, interchangeability.BSISO10372:1992 BSI 05-1999 1 Introduction In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit. Typical components found in such systems include servovalves. 1 Scope This International Standa

17、rd specifies the dimensions of surfaces on 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. t

18、hose in which the pilot stage is supplied 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 application, either service port (AandB) may be omitted. Because there is n

19、o clear distinction between servovalves and certain proportional control valves in performance and/or application, the existence of this mounting surface for servovalves does not exclude the use of a mounting surface as specified inISO4401. 2 Normative references The following standards contain prov

20、isions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid.
