In general applications, a fluid (liquid or gas) may be conveyed under pressure. Components are connected thro

22、ugh their threaded ports by fluid conductor connectors to tubes and pipes or to hose connectors and hoses. Ports are an integral part of fluid power components, such as pumps, motors, valves, cylinders, etc. For threaded ports and stud ends specified in new designs in hydraulic fluid power applicati

23、ons, ISO/TC 131/SC 4 recommends that the ISO 6149 series be used because these International Standards specify ports and stud ends with metric threads and O-ring sealing and because the subcommittee would like to help users by recommending one preferred system. ISO/TC 131/SC 4 further recommends tha

24、t threaded ports and stud ends in accordance with the ISO 1179 series, ISO 9974 series and ISO 11926 series not be used for new designs in hydraulic fluid power applications; these International Standards are maintained because they specify ports and stud ends that are currently used in hydraulic sy

25、stems worldwide. 3 EN ISO 6149-1:2007 (E) 1 Scope This part of ISO 6149 specifies dimensions for metric ports for use with the adjustable and non-adjustable stud ends detailed in ISO 6149-2 and ISO 6149-3. Ports in accordance with this part of ISO 6149 may be used at working pressures up to 63 MPa 6

26、30 bar1) for non-adjustable stud ends and 40 MPa (400 bar) for adjustable stud ends. The permissible working pressure depends upon port size, materials, design, working conditions, application, etc. See ISO 6149-2 and ISO 6149-3 for pressure ratings. Users of this part of ISO 6149 should ensure that

27、 there is sufficient material around the port to maintain the pressure. NOTE The Introduction of this part of ISO 6149 gives recommendations for ports and stud ends to be used for new designs in hydraulic fluid power applications. 2 Normative references The following referenced documents are indispe
