When pressure red
22、uction or pressure regulation is required, regulators and filter-regulators are components designed to maintain the pressure of the gas at an approximately constant level. It is therefore necessary to know some performance characteristics of these components in order to determine their suitability f

24、specifies which characteristics of compressed air pressure regulators are to be included in literature from their suppliers. It also applies to filter-regulators. This part of ISO 6953 applies to manually controlled direct operated types (with or without relieving mechanism), manually controlled int
25、ernal pilot operating types (e.g. nozzle flapper), and external pilot operated types. In addition, it specifies the product marking requirements for pressure regulators and filter-regulators. This part of ISO 6953 is applicable to compressed air pressure regulators with a rated inlet pressure of up
26、to 2 500 kPa (25 bar) and an outlet adjustment pressure of up to 1 600 kPa (16 bar); and to filter-regulators with rated inlet and outlet pressures of up to 1 600 kPa (16 bar), in which the major contaminants are removed by mechanical means. NOTE 1 1 bar = 0,1 MPa = 10 5Pa; 1 MPa = 1 N/mm 2 . The ra
27、ted pressure should be selected from the preferred pressures listed in ISO 2944. NOTE 2 The main characteristics to be included in the suppliers literature related to electrically modulated pneumatic continuous pressure control valves are specified in ISO 10094-1. 2 Normative references The followin

44、) 4.2.2 Port forms Port forms should be selected from ISO 16030 or ISO 1179 (all parts) for ports with pipe parallel threads, or from ISO 7-1 for ports with pipe-tapered threads. The connecting interface for flange-mounted designs can be plain ported and counter bored to accept O-rings. For certain
45、applications and connections, other port forms can be employed. NOTE Annex A describes thread forms from the former ISO 1179:1981. 4.2.3 Rated pressure Compressed air pressure regulators and filter-regulators shall be classified according to their rated pressure, selected from ISO 2944.
